Merino and cashmere are the two premium natural fibres brands most often weigh against each other when speccing winter knitwear, and the numbers behind them look very different. Global merino output ran to roughly 200,000 tonnes in 2024, while cashmere reached just 25,000 tonnes: about eight times less fibre, at prices four to twelve times higher (IWTO, 2024). Both feel good next to skin. Only one behaves well when your customer wears it three times a week.
This guide covers what each fibre actually is, how they compare at the fibre level, what they cost at Portuguese mills in 2026, and which Portuguese factories can produce them at the volumes brands typically need. Everything reflects the manufacturer-side view from sweater and knitwear runs coordinated across our factory group.
Heads up: We're Portugal Clothing Factory, a group of Portuguese garment factories in the northern textile cluster (Porto, Guimarães, Braga, Barcelos, Famalicão). The pricing, MOQs, and production observations below come from merino and cashmere runs coordinated across the group between 2024 and 2026, plus the trade sources cited throughout.
Key Takeaways
- Cashmere fibres measure 14 to 19 microns; merino runs 17 to 24 microns, which is why cashmere feels softer but merino wears longer
- Cashmere is roughly twice as warm per gram as merino at equal knit weight (Cashmere and Camel Hair Manufacturers Institute, 2024)
- Portuguese yarn prices in 2026: merino €22 to €90 per kilo, cashmere €80 to €320 per kilo
- [ORIGINAL DATA] Only 6 of 25 verified factories in our group offer cashmere production, versus 14 offering merino (PCF factory group data, July 2026)
- A 70/30 merino/cashmere blend delivers roughly 85% of cashmere's hand-feel at 45% of the yarn cost

What Are Merino Wool and Cashmere, Really?
Merino wool is shorn from merino sheep. Cashmere is combed from the fine undercoat of the cashmere goat. Sheep produce 3 to 6 kilograms of usable fleece per year; a single cashmere goat yields just 150 to 250 grams of finished fibre after dehairing (Sustainable Fibre Alliance, 2024). That single ratio, roughly 20 to 1, explains most of the price gap.
Merino sheep were originally Spanish. Australia now produces about 80% of the world's fine merino, with New Zealand, South Africa, and Patagonia supplying most of the certified ethical volume. Cashmere goats live on the Central Asian steppe, where winter temperatures reach minus 40 degrees Celsius and the goats grow a downy undercoat to survive. Mongolia and China together produce roughly 90% of global cashmere (Textile Exchange, 2024).
Both fibres are keratin proteins. Both crimp, insulate, and absorb moisture. But the animal, the climate, the harvest method, and the annual yield are so different that the two fibres end up serving different roles in a collection.
Citation Capsule: Merino wool is shorn once a year from merino sheep, mainly in Australia. Cashmere is hand-combed each spring from the fine undercoat of cashmere goats in Mongolia and China. Sheep yield 3 to 6 kilograms of usable wool per year; a cashmere goat produces just 150 to 250 grams. The 20:1 yield gap drives most of the retail price difference (Sustainable Fibre Alliance, 2024).
How Do Merino and Cashmere Compare at the Fibre Level?
Fibre diameter is the single number that drives softness, and it separates these two more than any marketing copy. Cashmere sits at 14 to 19 microns, with premium grades under 16 microns; merino runs 17 to 24 microns, with superfine grades under 19 microns (Woolmark, 2023). Both clear the 22-micron "itch threshold" comfortably at their best grades.
The other fibre-level differences matter for design, not just for feel. Cashmere is shorter in staple length (35 to 45 mm) than merino (60 to 100 mm), which is why cashmere yarn breaks more easily under tension and why cashmere sweaters pill more. Merino's longer staple lets the yarn hold together at high knitting speeds, which is why Icebreaker can produce a merino tee at fast-fashion volume and no one produces a cashmere tee at that scale.
Crimp and loft
Merino has 15 to 30 crimps per centimetre; cashmere has fewer. That means merino traps more air per gram at typical knit weights, which is why superfine merino base layers work in both winter and summer. Cashmere's lower crimp gives it a smoother, denser hand and a distinctive drape.
Staple length
Long staple equals durable yarn. Merino at 60 to 100 mm spins into robust worsted yarn that survives washing and daily wear. Cashmere at 35 to 45 mm spins into softer but weaker woollen-count yarn, which is why cashmere is typically knitted at heavier gauges and washed with more care.
Which Fibre Feels Softer Against Skin?
Cashmere wins on softness at equal grade, full stop. In blind hand-feel panels run by the Woolmark Company, cashmere scored roughly 15 to 20% higher on softness ratings than 17.5-micron superfine merino, even though the micron gap is only 3 to 4 units (Woolmark, 2023). Fibre diameter, staple smoothness, and lower crimp density all contribute.
That said, ultra-fine 17.5-micron merino sits closer to cashmere than most buyers expect. In our own factory group sampling, brand founders in a blind-touch test typically pick 17.5-micron merino as "cashmere" about 25% of the time. The gap is real, but at premium tiers it's smaller than the price tag suggests.
Where merino loses is in that first-touch impression at retail. Cashmere reads as luxury the moment a customer picks the garment off the shelf. That perception drives conversion. If your brand sells on hand-feel in a store, cashmere earns its price. If it sells on performance or online, superfine merino usually clears the bar.
Which Is Warmer per Gram?
Cashmere insulates roughly twice as effectively as merino at equal fabric weight, according to comparative thermal-resistance testing published by industry bodies (Cashmere and Camel Hair Manufacturers Institute, 2024). The finer, hollow-structured undercoat traps more still air per gram, which is what actually creates warmth in a knit garment.
That single ratio is why cashmere scarves and beanies punch above their weight. A 200-gram cashmere scarf keeps a wearer warmer than a 300-gram merino scarf at equivalent knit density. For accessories where weight and packability matter, cashmere's warmth-to-weight ratio is genuinely hard to beat.
For sweaters, the practical implication is different. Winter jumpers are usually specced at 350 to 500 GSM anyway, at which point both fibres are warm enough. The customer feels the extra insulation of cashmere as "cosiness", but they aren't cold in a merino sweater at the same gauge. Warmth-to-weight matters most when weight actually matters, which is scarves, beanies, and travel-friendly knits.
Citation Capsule: At equal fabric weight, cashmere delivers roughly twice the thermal insulation of merino wool, because its finer, hollow-structured fibre traps more still air per gram (Cashmere and Camel Hair Manufacturers Institute, 2024). Merino compensates through higher crimp and better moisture management, which is why it dominates active winter categories where cashmere would over-insulate.
How Do They Compare on Durability and Pilling?
Merino wears longer than cashmere, and it isn't close. Standard product testing shows merino sweaters withstand roughly 15,000 to 20,000 Martindale abrasion cycles before visible wear, while cashmere sweaters typically fail between 8,000 and 12,000 cycles (Woolmark, 2023). Longer staple length and lower fibre-end density drive the gap.
Pilling is where the durability difference shows up first for the customer. All animal fibres pill, but cashmere pills faster because its shorter staple leaves more fibre ends at the fabric surface. Those loose ends tangle under friction (armpit, cuff, backpack strap) and form the pills customers complain about within weeks.
Merino, thanks to its longer staple and higher crimp, holds its yarn structure much better. A well-specced merino sweater at 19 micron pills mildly in year one and stabilises. A cashmere sweater at the same gauge often needs a de-piller after 10 wears.
What this means for warranties
Brands that offer generous returns or lifetime repair should think carefully about running heavy cashmere programmes without a pilling caveat in their care instructions. In our factory group data, roughly 8% of returned cashmere garments in 2024-2025 cited "pilled after few wears" as the reason, versus under 2% for merino at similar retail price points.
Which Handles Moisture and Odour Better?
Merino manages moisture and odour meaningfully better than cashmere, which is why it dominates base layers and sportswear where cashmere never appears. Merino absorbs up to 30% of its own weight in moisture vapour before feeling wet, and its keratin structure binds odour molecules over multiple days of wear (Woolmark, 2023). Cashmere absorbs slightly less and dries more slowly.
The mechanism is the same for both fibres: hygroscopic keratin protein pulls water vapour into the fibre core rather than holding it on the surface. But merino's higher crimp and longer staple move water through the yarn faster. A merino base layer can be worn three or four days without odour build-up. A cashmere garment worn the same way starts to feel damp against the skin.
This is why every serious performance brand (Icebreaker, Smartwool, Ashmei) works in merino and none of them work in cashmere. Cashmere isn't a performance fibre. It's a comfort fibre.
Rhetorical check: if cashmere were a technical fibre, would luxury brands really cede that market to merino? They tried in the 1990s. It didn't work.
What Does Each Fibre Cost in Portugal?
Merino yarn at Portuguese mills in 2026 runs €22 to €90 per kilogram; cashmere yarn runs €80 to €320 per kilogram, with baby cashmere at the top end (ATP, 2025). The 3 to 4 times price gap on entry-grade yarn widens further at the premium end, where certified ultra-fine merino tops out around €90 while single-origin Mongolian baby cashmere clears €300.
The translation to finished-garment cost is more useful than the raw yarn number. A mid-weight crewneck sweater uses roughly 500 grams of yarn. At €35 per kilo merino, the yarn cost is €17.50; at €120 per kilo Grade B cashmere, it's €60. Add CMT, finishing, packaging, and duty, and the wholesale price gap widens to €35-plus per unit.
Cost per finished sweater at Portuguese factories
| Fibre / Blend | Yarn cost (500g garment) | CMT (400 GSM) | Total FOB estimate |
|---|---|---|---|
| Standard merino (19.5 μ) | €12 to €22 | €18 to €28 | €35 to €58 |
| Superfine merino (18.5 μ) | €15 to €30 | €22 to €32 | €42 to €68 |
| Merino/cashmere 70/30 | €30 to €65 | €25 to €38 | €62 to €108 |
| Cashmere Grade C | €40 to €60 | €28 to €42 | €75 to €112 |
| Cashmere Grade A | €75 to €110 | €35 to €55 | €125 to €175 |

Which Portuguese Factories Can Actually Produce Each?
Merino is widely available in Portugal; cashmere is genuinely scarce at production scale. [ORIGINAL DATA] Of the 25 verified active knitwear producers in our documented factory group as of July 2026, 14 offer merino production, and only 6 offer cashmere. The gap reflects machinery specialisation, not market demand.
Cashmere requires specialist flat-bed knitting machines calibrated for weaker, shorter-staple yarn. Speeds run 30 to 40% slower than equivalent merino production, tension settings differ, and needle-gauge tolerances are tighter. Factories that don't already run cashmere rarely add it because payback on the machine calibration only works at consistent volume.
| Capability | Merino-capable factories | Cashmere-capable factories |
|---|---|---|
| Count in our group (25 total) | 14 | 6 |
| Typical MOQ | 200 to 500 units | 100 to 300 units |
| Machinery type | Standard flat-bed / circular | Fine-gauge flat-bed, specialist calibration |
| Lead time (sweater) | 8 to 11 weeks | 10 to 14 weeks |
| CMT for 400 GSM sweater | €18 to €32 | €28 to €55 |
| Certifications available | RWS, ZQ, Woolmark | SFA cashmere, GRS (recycled) |
Sources: PCF factory group data (2024-2026), industry references.
MOQ is lower on cashmere because the yarn cost is so high that yarn minimums dominate. A 100-unit cashmere run at 500 grams per garment already books 50 kilograms of yarn, which is typically enough to satisfy the mill.
Citation Capsule: Portuguese cashmere production is concentrated in a small number of specialist knit factories. In our documented factory group of 25 verified active knitwear producers, 6 offer cashmere versus 14 offering merino. Lead times run 10 to 14 weeks for cashmere versus 8 to 11 for merino, driven by both yarn booking cycles and slower fine-gauge knitting speeds (ATP, 2025).
Is Merino or Cashmere More Sustainable?
Neither fibre is straightforwardly "greener", and the honest answer depends on which impact you weight most. Roughly 45% of European premium apparel brands now specify mulesing-free wool in supplier contracts, up from 18% in 2020 (Textile Exchange, 2024). Cashmere faces a different but equally serious issue: overgrazing on Mongolian and Chinese steppes has degraded roughly 70% of Mongolia's grasslands (Sustainable Fibre Alliance, 2024).
Merino's certification landscape is mature. RWS (Responsible Wool Standard) and ZQ Merino both cover mulesing-free supply, animal welfare, land management, and chain of custody. Certified merino yarn adds 15 to 30% at the yarn level, which is a manageable premium at wholesale.
Cashmere's certification is less mature. The Sustainable Fibre Alliance (SFA) Cashmere Standard covers responsible grazing, herder livelihoods, and animal welfare, but adoption is still under 15% of global cashmere production. Recycled cashmere (GRS-certified) is the fastest-growing sustainable option, using post-industrial cashmere waste at 30 to 60% blend ratios.
Land impact
One kilogram of raw cashmere requires the grazing output of roughly 4 to 5 goats over a year. One kilogram of merino wool takes the grazing output of less than half a sheep. Per kilogram of finished fibre, cashmere's land footprint is 8 to 10 times higher than merino's (Textile Exchange, 2024).
Emissions
Both fibres carry meaningful emissions from methane and land-use change. Recycled options for both (recycled cashmere in particular) cut emissions by 60 to 80% versus virgin, and are worth serious consideration for founder brands building sustainability positioning.
When Should You Blend Instead of Choose?
Blending is where most brands land in practice, and the 70/30 merino/cashmere ratio is the sweet spot for a reason. At that ratio, hand-feel testing shows blends deliver roughly 85% of pure cashmere's softness rating at 45% of the yarn cost (Woolmark, 2023). Durability improves dramatically over pure cashmere too, because merino's longer staple stabilises the yarn.
Common blend logic across Portuguese production:
- 90/10 merino/cashmere: perceived as merino, with a soft top note. Used for premium base layers and lightweight sweaters where cost discipline matters.
- 80/20 merino/cashmere: genuinely improved hand-feel over pure merino, still robust. Popular in wholesale premium sweaters at €120 to €180 retail.
- 70/30 merino/cashmere: the price/performance sweet spot. Reads as cashmere in the store, wears like merino at home.
- 50/50 merino/cashmere: premium territory, closer to cashmere in feel but with durability benefits.
- Pure cashmere: flagship, ultra-luxury tier only.
Blends also solve a certification problem. It's easier to source certified merino at volume than certified cashmere, so a 70/30 blend gets you closer to a clean supply story than pure cashmere typically allows.
Citation Capsule: A 70/30 merino/cashmere blend delivers roughly 85% of pure cashmere's softness rating at 45% of the yarn cost, and improves durability meaningfully thanks to merino's longer staple length. It has become the dominant premium-tier blend in Portuguese knitwear production because it lands the retail hand-feel test while keeping wholesale margins workable (Woolmark, 2023).
Which Garments Suit Merino, Cashmere, or a Blend?
Category fit is the last decision, and it usually resolves itself once you list intended wear frequency. Global merino apparel splits roughly 42% knitwear, 25% suiting, 20% base layers, and 13% other; cashmere is over 75% sweaters, scarves, and beanies (Woolmark, 2023). The categorisation reflects each fibre's real strengths.
Where merino wins:
- Base layers, running shirts, cycling jerseys
- Socks (durability and odour resistance)
- Everyday cardigans and pullovers under €150 retail
- Fine-gauge shirts, T-shirts, transitional layers
- Suiting fabric (worsted, tropical wool)
Where cashmere wins:
- Flagship winter sweaters at €200-plus retail
- Scarves, wraps, and stoles
- Beanies and berets
- Loungewear and premium travel knits
- Luxury dressing gowns and layered indoor wear
Where blends win:
- Mid-price premium sweaters (€120 to €180 retail)
- Cardigans that need daily-wear durability with a soft hand
- Wholesale programmes with a cashmere story but tight margins
- Knitwear collections that need to survive a rental or resale market
Reference brands worth studying
Merino specialists: Icebreaker, Smartwool, John Smedley (fine-gauge merino for over 240 years), Wool& for dresses. Cashmere specialists: Loro Piana, Brunello Cucinelli, Extreme Cashmere for modern volumes, Naadam for direct-source Mongolian. Blend leaders: Uniqlo (merino/cashmere at scale), Everlane, &Daughter.
Production observation: across our factory group between 2024 and 2026, pure-cashmere orders declined slightly as a share of premium knitwear volume, while 70/30 and 80/20 blends grew roughly 35% year-over-year. Younger founder brands are treating cashmere as an ingredient rather than a hero material, and it's a genuinely healthier commercial strategy for anyone under €50M revenue.
Portuguese textile cluster overview
Which Portuguese mills spin and knit merino and cashmere yarn?
Roughly 82% of merino and cashmere sweater programmes coordinated through PCF factories in 2024-2026 source yarn from four anchor mills in the northern cluster, with Italian and Scottish spinners covering premium tiers (ATP, 2025). Portugal's knit base sits in Guimarães, Braga, and Barcelos, with Riopele and Somelos handling the bulk of wool blend spinning and Impetus and Troficolor covering knit-side production.
Named mill directory for winter knitwear
| Mill or spinner | Region | Specialty | Yarn tier |
|---|---|---|---|
| Riopele | Famalicão | Wool, wool/cashmere blends, worsted spinning | Standard merino to Grade B cashmere |
| Somelos | Guimarães | Yarn-dyed wovens, worsted wool, fine-gauge | Standard to superfine merino |
| Impetus | Barcelos | Fine-gauge knitwear, jersey, base layers | Superfine merino (18-19 μ) |
| Troficolor | Famalicão | Recycled cashmere, GRS wool blends | Recycled cashmere at 30-60% blends |
| Coelima | Guimarães | Milled wool, boiled wool, home-textile crossover | Coarse merino |
| Cariaggi (IT import) | Cagli, Italy | Ultra-fine cashmere spinning, Loro Piana supplier | Grade A cashmere, baby cashmere |
| Todd & Duncan (UK import) | Kinross, Scotland | Cashmere spinning for premium knitwear | Grade A cashmere, mulesing-free story |
Sources: ATP mill directory (2025), PCF factory group orders (2024-2026), individual mill/spinner disclosures.
Riopele and Somelos supply roughly 60% of the merino yarn PCF factories run through sweater programmes in the 19-22 micron band. For 18-micron superfine merino and Grade A cashmere, most orders route through Italian spinners (Cariaggi, Zegna Baruffa) with knitting done in Portugal. Troficolor now leads the recycled cashmere blend category in the Portuguese cluster.
Micron grade side-by-side
Micron grade is the single number that predicts hand-feel across both fibres. Cashmere sits at 14.5-16 microns for premium grades, 16-18 microns for standard grades. Merino sits at 17.5 microns for ultra-fine, 18.5-19.5 for superfine, 21-24 for standard. Yarn count (Nm) sits at 2/28 to 2/60 depending on gauge, and knitting gauge itself ranges from 3gg for chunky hand-knit look to 16gg for fine flat-knit.
| Metric | Superfine merino | Standard merino | Grade B cashmere | Grade A cashmere | Baby cashmere |
|---|---|---|---|---|---|
| Fibre diameter | 17.5-18.5 μ | 19.5-22 μ | 16-18 μ | 14.5-16 μ | 13-14.5 μ |
| Staple length | 60-90 mm | 60-100 mm | 32-38 mm | 38-45 mm | 34-42 mm |
| Yarn count typical | 2/48 Nm | 2/28 Nm | 2/28 Nm | 2/48 Nm | 2/60 Nm |
| Common knit gauge | 12-16gg | 7-12gg | 7-12gg | 12-16gg | 14-18gg |
| EUR per kg 2026 | €55-€90 | €22-€45 | €80-€130 | €180-€260 | €260-€380 |

EUR yarn cost at Portuguese mill minimums
Yarn minimums drive the price ladder on smaller programmes. First-run 50 kg orders sit 20-35% above 500 kg repeats, and cashmere yarn minimums are higher per colour (typically 30-50 kg minimum) than merino (typically 15-25 kg).
| Yarn tier | 50 kg minimum | 150 kg minimum | 500 kg minimum |
|---|---|---|---|
| Standard merino (19.5 μ, 2/28 Nm) | €32-€38/kg | €26-€30/kg | €22-€26/kg |
| Superfine merino (18.5 μ, 2/48 Nm) | €70-€90/kg | €60-€72/kg | €55-€65/kg |
| Merino/cashmere 70/30 | €110-€140/kg | €90-€110/kg | €75-€90/kg |
| Cashmere Grade B (16-18 μ) | €130-€160/kg | €110-€125/kg | €90-€105/kg |
| Cashmere Grade A (14.5-16 μ, Cariaggi) | €240-€280/kg | €200-€230/kg | €180-€200/kg |
| Recycled cashmere (Troficolor, 40% blend) | €55-€70/kg | €45-€55/kg | €38-€45/kg |
Sources: PCF factory group quotes (2024-2026), Cariaggi and Todd & Duncan yarn cards (2026), Troficolor recycled programme (2026).
Citation Capsule: Riopele and Somelos supply roughly 60% of the merino yarn PCF factories run through sweater programmes at 19-22 microns. Grade A cashmere at 14.5-16 microns typically ships from Cariaggi (Italy) or Todd & Duncan (Scotland) with knitting done in Portugal. Troficolor leads the recycled cashmere blend category in the Portuguese cluster, with 40% recycled blends running EUR 38-70 per kg at 50-500 kg minimums, per PCF factory group data (2024-2026).
What certifications and mill grades should winter knits carry?
Winter knit certification stacks now average 2.6 certifications per SKU at European premium retail, up from 1.1 in 2020 (Textile Exchange, 2024). OEKO-TEX Standard 100 is baseline for chemical safety; RWS covers wool welfare; SFA covers cashmere; Cashmere Mark (CCMI) verifies 100% cashmere content; GRS certifies recycled fibres. For premium positioning, Cariaggi and Todd & Duncan mill grades act as their own certification proxies.
The certification stack a 2026 winter knit should hold
| Certification / mill mark | Scope | When to specify | Cost impact |
|---|---|---|---|
| OEKO-TEX Standard 100 | Chemical safety on finished yarn or fabric | Every knit, baseline | 0-2% premium |
| RWS | Responsible Wool Standard, farm to fabric | Merino with animal welfare positioning | 6-10% yarn premium |
| ZQ Merino | New Zealand ethical merino programme | Merino with New Zealand traceability | 8-12% premium |
| Cashmere Mark (CCMI) | Verified 100% cashmere content | Pure cashmere programmes | 3-6% yarn premium |
| SFA Cashmere | Sustainable Fibre Alliance grazing standard | Cashmere with land-impact story | 6-12% premium |
| GRS | Global Recycled Standard | Recycled cashmere, recycled wool | 6-10% premium |
| Woolmark | Wool composition and quality mark | Any wool programme | 1-3% premium |
| Cariaggi mill grade | Italian spinner premium tier | Grade A cashmere hero SKUs | Priced in yarn |
| bluesign | Chemistry across wet-processing | Technical knitwear, dyed programmes | 5-12% premium |

Common founder mistakes on winter knit programmes
- Speccing pure cashmere without a pilling caveat. Grade B cashmere pills within 10 wears at friction zones. Move to a 70/30 blend or set customer expectations on the care label.
- Ordering below yarn minimums. A 100-unit run at 500g per garment uses 50 kg of yarn, which sits at the minimum for most Grade A cashmere colours. Below that, expect surcharges or colour restrictions.
- Confusing Grade A cashmere with baby cashmere. Grade A sits at 14.5-16 microns; baby cashmere sits at 13-14.5 microns and costs 40-60% more per kg. Verify with the spinner's yarn card.
- Skipping the RWS or Cashmere Mark on premium positioning. European retailers now audit certification chains before onboarding. Retrofit costs 3x more than day-one specification.
Citation Capsule: Winter knit programmes now average 2.6 certifications per SKU at European premium retail (Textile Exchange, 2024). A 70/30 merino/cashmere blend at 2/48 Nm on 7-12gg knitting, spun through Cariaggi and knitted at Riopele or Somelos, hits the mid-premium sweater sweet spot at EUR 140-200 retail with an RWS + CCMI + OEKO-TEX certification stack.
Frequently Asked Questions About Merino vs Cashmere
Is cashmere really warmer than merino wool?
Yes, roughly twice as warm per gram at equal knit density, according to comparative thermal-resistance testing (Cashmere and Camel Hair Manufacturers Institute, 2024). The gap comes from cashmere's finer, hollow-structured undercoat fibre, which traps more still air. At sweater weights (350 to 500 GSM) the practical warmth of both fibres is more than enough for most winter conditions.
Which is more expensive per finished sweater in Portugal?
Cashmere costs 2 to 4 times more per finished sweater than merino at equivalent quality. A mid-weight superfine merino crewneck FOBs around €42 to €68 at Portuguese factories; a Grade C cashmere sweater lands at €75 to €112, and Grade A cashmere reaches €125 to €175 for the same silhouette (ATP, 2025). Yarn cost drives most of the gap.
Does merino pill less than cashmere?
Yes, meaningfully. Merino sweaters withstand roughly 15,000 to 20,000 Martindale abrasion cycles before visible wear; cashmere typically fails between 8,000 and 12,000 cycles (Woolmark, 2023). Cashmere's shorter staple length leaves more fibre ends at the fabric surface, which is where pilling starts. A 70/30 merino/cashmere blend cuts pilling risk meaningfully.
Can Portuguese factories produce both fibres?
Both, but cashmere is much less widely available. In our documented factory group of 25 verified knitwear producers, 14 offer merino and only 6 offer cashmere as of July 2026. Cashmere requires specialist fine-gauge flat-bed calibration, slower knitting speeds, and tighter tension control, which is why fewer factories carry it (PCF factory group data, 2026).
Is a merino-cashmere blend worth it?
For most premium sweater brands, yes. A 70/30 merino/cashmere blend delivers roughly 85% of pure cashmere's softness rating at 45% of the yarn cost, and improves durability significantly (Woolmark, 2023). It's the dominant premium blend across Portuguese production because it lands the retail hand-feel test while keeping wholesale margins workable.
Which fibre is more sustainable?
Neither is unambiguously greener. Merino has mature certifications (RWS, ZQ) covering mulesing-free supply and animal welfare, adopted by roughly 45% of European premium brands (Textile Exchange, 2024). Cashmere faces overgrazing pressure on Mongolian and Chinese grasslands, with 70% of Mongolia's steppes degraded. Recycled cashmere and SFA-certified virgin cashmere are the strongest options.
What MOQ should I expect at Portuguese cashmere factories?
Typical cashmere MOQs at Portuguese factories run 100 to 300 units per style, lower than merino's 200 to 500 units. The reason is counterintuitive: cashmere yarn is so expensive that even 100 units already books enough yarn to satisfy mill minimums (roughly 50 kg per colour). Lead times run 10 to 14 weeks, mostly driven by yarn booking cycles.

Conclusion: Which One Should You Actually Spec?
Merino wins on durability, moisture management, cost, and category breadth. Cashmere wins on hand-feel, warmth-to-weight, and retail perception. If you're building a base layer, sock, sportswear, or under-€150 sweater programme, merino is almost always the right answer, ideally at superfine 18.5-micron with RWS or ZQ certification. If you're building a flagship €250-plus sweater or a scarf and accessory line, cashmere earns its price.
For everything in the middle, and it's a large middle, the honest answer is a merino/cashmere blend at 70/30 or 80/20. It's the ratio Portuguese factories run most often for a reason: it delivers the store-shelf test at a wholesale margin most brands can actually sustain. Start there, then flex up or down as your customer data comes in.
