- Organic cotton fleece — n/a
Why the swap works
Wool insulates, wicks moisture and resists odour — properties of the fibre's crimped, scaly structure. Plant and synthetic fibres cover the same ground piecewise. Organic cotton and hemp breathe well for everyday wear; bamboo lyocell and Tencel drape softly for base layers; recycled polyester fleece and PrimaLoft-style synthetics match wool's warmth-to-weight for outdoor use; and acrylic or cotton-acrylic blends knit like wool for jumpers and socks. The performance gap is narrowest in everyday clothing and widest in technical outdoor gear, where merino's odour resistance on multi-day trips is genuinely hard to match — though modern synthetic base layers come close and dry faster. For knitters, plant yarns (cotton, bamboo, linen) and acrylics substitute at the same gauge with different drape.

- Layer thin fabrics rather than one thick one
- Look for recycled content percentages
- Second-hand is the lowest-impact choice
Avoid
- Assuming "responsible wool" means no slaughter
- Buying thin acrylic that pills in a season
Three dishes with the swap applied
Cold-weather layering without wool
Synthetic or Tencel base layer, recycled-fleece mid layer, waterproof shell — the same system as wool, drying faster.
Knitting a wool-free jumper
Substitute cotton-acrylic blend yarn at the same weight; swatch first since plant fibres drape heavier than wool.
Wool-free socks
Look for bamboo or synthetic hiking socks with terry cushioning; they wick and cushion comparably.
Questions people ask
Is wool not just a haircut?
Sheep are bred for unnatural fleece volume, mulesed in some regions and slaughtered when yields drop.
What is warmest without wool?
Recycled polyester fleece or a down-free synthetic insulation layer.
Isn't wool just a haircut?
Commercial sheep farming involves more than shearing — mulesing, selective breeding for wrinkled skin, and slaughter when wool quality declines — which is why vegans avoid it.
What replaces merino for hiking?
Synthetic base layers (recycled polyester) wick and insulate comparably and dry faster; they hold odour more, so wash or air them more often.
Are 'recycled wool' and 'peace wool' vegan?
Recycled wool is still animal fibre, so most vegans avoid it; the same applies to any wool regardless of welfare claims.

A substitution is not a nutrition guarantee
Choose a replacement for the job the original ingredient performs: binding, aeration, thickening, fat or flavour. A mushroom can imitate a patty's shape while providing much less protein; a nut cream can mimic dairy texture without its calcium or B12 fortification. Check the actual product and the rest of the meal.
Ratios are starting points unless a complete recipe has been tested with that exact replacement. Brand formulation, water content and cooking method change the result. Try a small batch for important bakes, and check soy, nuts, sesame and wheat allergens even when a product is labelled vegan.
