Vegan Clothing Materials and How to Spot Them
Ten fibres in common use come from animals. Everything else on a rail is plant, mineral, or synthetic. The harder part of a wardrobe check is rarely the main fabric — it is the button, the trim, the lining, and the one EU label phrase most people have never noticed.
Start with the short list
Checking a wardrobe goes faster from the other direction. Rather than verifying that forty fabrics are fine, learn the ten that come from animals.
| Material | Comes from |
|---|---|
| Wool | Sheep, including merino |
| Cashmere | The undercoat of cashmere goats |
| Mohair | Angora goats |
| Angora | Angora rabbits |
| Alpaca | Alpacas |
| Camel hair | Bactrian camels |
| Silk | Silkworm cocoons |
| Down | Duck and goose feathers |
| Leather | Animal hide |
| Wool felt | Matted wool fibre |
Three names cause more confusion than the rest. Suede and shearling are leather in a different finish, so they belong on the list without qualification. Velvet is a weave rather than a fibre — it can be silk, cotton, viscose, or polyester, and only the composition label settles it. Felt is the quiet one: traditional felt is wool, synthetic craft felt is polyester, and the two are nearly indistinguishable on a shelf.
Everything past those ten is plant, mineral, or synthetic. That covers the overwhelming majority of what hangs on a rail.
The four families that are fine
Plant fibres
Grown, harvested, spun. The oldest category and the easiest to verify.
Organic cotton, conventional cotton, recycled cotton, linen, hemp, jute, ramie, and lotus fabric.
Hemp and linen carry the strongest environmental case in this group — both grow with modest water and little pesticide input, and both have improved substantially in softness through modern processing. Conventional cotton sits at the other end on water and chemical use, which is a separate concern from animal content and worth holding in view.
Regenerated cellulosics
Wood pulp or cotton waste dissolved and re-spun into fibre. Plant-derived, chemically processed.
TENCEL / Lyocell, modal, viscose and rayon, cupro, bamboo viscose, acetate, and SeaCell.
Lyocell stands out because the solvent runs in a closed loop and is recovered rather than discharged. Conventional viscose production has a poorer record on solvent handling and forestry sourcing, so the FSC mark is a useful companion signal on this family.
Synthetics
Petrochemical polymers, extruded and spun.
Polyester, recycled polyester, nylon, Econyl, acrylic, spandex, microfiber, neoprene, synthetic fleece, Gore-Tex, and Ultrasuede.
These carry no animal content and do carry a microplastic cost. Every wash releases fibres, and fleece is among the heaviest shedders. Econyl and recycled polyester improve the feedstock story by starting from waste, and neither changes the shedding. A filter bag in the machine does more about this than a fibre swap.
Leather alternatives
The fastest-moving category, and the one where marketing language runs furthest ahead of the material.
PU leather and PVC leather are the established options: a polymer coating on a fabric backing. PU has largely displaced PVC in apparel on both performance and environmental grounds.
The newer entrants build from agricultural waste or fungi. Piñatex uses pineapple leaf fibre, cactus leather uses nopal, apple leather and mango leather use fruit processing waste, cork leather uses harvested bark, and Mylo and Muskin are grown from mycelium.
One honest caveat applies across most of this group: the bio-based content is usually a layer, bonded with a polymer binder onto a textile backing. A material advertised as cactus leather may be well under half cactus by weight. That does not make it a bad material — it makes the marketing shorthand imprecise, and the brand’s technical specification is where the real composition appears.
The parts that slip past
The main fabric is the easy half. Most misses happen at the edges of a garment.
The label phrase that matters. Regulation (EU) No 1007/2011 requires the words “Contains non-textile parts of animal origin” whenever a product includes an animal-derived component outside the fabric itself. That covers leather patches on jeans, horn and bone buttons, fur trim on a hood, leather pulls on a zip, and bone toggles on a coat. The UK retained equivalent requirements. It is one line in small print, it is legally mandatory, and it catches exactly the things a composition list misses.
Where to look on a specific garment:
- Buttons — horn, bone, and mother of pearl all appear on mid and premium tailoring
- Trims and patches — the leather brand patch on denim is the classic case
- Linings and interlinings — silk linings on jackets, and wool or horsehair canvas in structured tailoring
- Fill — down in coats, duvets, and pillows
- Footwear adhesives — collagen-based glues have a long history in shoemaking, though synthetics dominate current production
- Shell finishes — some waxed and waterproofed finishes have historically used animal waxes
Composition percentages. The same regulation requires fibre content by percentage of weight. A jumper listing 5% wool contains wool. Marketing terms such as wool-feel, cashmere-touch, and silky carry no legal definition and appear precisely because the fibre itself is absent.
Certifications that help here
No mark answers every question, and each covers a different axis.
- GOTS — organic fibre with a full supply-chain audit, and the strictest textile scheme in this reference
- The Vegan Society Trademark — covers clothing alongside food and cosmetics
- OEKO-TEX Standard 100 — chemical safety rather than animal content
- Global Recycled Standard — verifies recycled content claims
- FSC — forestry sourcing behind the cellulosic fibres
Two marks are easy to misread. The Responsible Wool Standard and Responsible Down Standard both raise welfare floors substantially and both certify animal materials, so neither indicates a vegan product.
A two-minute wardrobe check
- Read the composition percentages. Ten fibre names decide it, and the rest of the list is fine.
- Find the non-textile animal parts line. One sentence, easy to miss, and it covers every trim.
- Look at the hardware. Buttons, patches, and zip pulls, especially on tailoring and denim.
- Check the lining and the fill. Jackets, coats, and bedding are where this hides.
- Treat feel words as noise. Wool-feel means no wool, which is useful information stated backwards.

Common questions
Frequently asked questions
Which fabrics are not vegan?
Ten come up regularly: wool, merino, cashmere, mohair, angora, alpaca, camel hair, silk, down, and leather. Wool felt belongs on the list too, since traditional felt is matted wool. Suede and shearling are forms of leather, and velvet can be silk or synthetic depending on the piece, so both need a composition check rather than a rule.
Is polyester vegan?
Polyester is made from petrochemicals with no animal input, so it is vegan by composition. The trade-off sits elsewhere: polyester sheds microplastic fibres in the wash and comes from fossil feedstock. Recycled polyester made from post-consumer bottles reduces the feedstock problem without solving the shedding.
Is viscose or rayon vegan?
Yes. Viscose, rayon, modal, cupro, and lyocell are all regenerated cellulosics, made by dissolving wood pulp or cotton linter and spinning it into fibre. No animal material is involved. The environmental questions attached to them concern forestry sourcing and solvent recovery rather than animal content.
What does contains non-textile parts of animal origin mean?
It is a mandatory phrase under EU textile labelling rules, required when a product includes an animal-derived component that sits outside the fabric itself — a leather patch, a horn or bone button, a fur trim, a bone toggle. The shell fabric can be entirely plant-based while this line quietly flags something on the garment that is not. It is the single most useful sentence on a clothing label and the easiest to skim past.
Is vegan leather just plastic?
Often, though the category has widened. PU and PVC leathers are polymer coatings on a fabric backing. Alongside them sit materials built from cactus, pineapple leaf fibre, apple and mango waste, cork, and mycelium. Many of these still use a polymer binder or backing, so the honest description is usually part bio-based rather than fully plant. The composition label and the brand's own technical sheet are where the real answer lives.
Are dyes and finishes on clothing vegan?
Nearly always. The overwhelming majority of textile dyes are synthetic, and animal-derived colourants such as carmine are vanishingly rare in modern apparel. Adhesives are the more realistic question in footwear, where collagen-based glues have a long history, though synthetic adhesives dominate current production. Brands with a vegan certification will have covered both.
