Wool, Down & Silk: Better or Not?

Wool: The Renewable Fibre With a Catch

Wool has a genuinely great resume. Sheep regrow their fleece every year, so it's renewable in a way oil-based polyester never will be. It's durable, naturally warm even when damp, and when a wool jumper finally wears out, it biodegrades in soil within a few years — synthetics can hang around for decades.

So what's the catch? It's called mulesing. In Australia, which grows most of the world's fine merino wool, some farmers remove strips of skin from around a lamb's rear to prevent flystrike, a painful parasite infection. It works, but it's often done without pain relief, and animal welfare groups have campaigned against it for years. New Zealand banned the practice in 2018, and a growing number of Australian farmers have moved away from it too.

This is where certifications come in. The Responsible Wool Standard (RWS), run by a nonprofit called Textile Exchange, bans mulesing entirely and audits how farms treat both their sheep and their land. So when a label says 'mulesing-free', it's making a specific, checkable claim — not just a cosy-sounding vibe. That pattern — a claim you can actually verify — is the theme of this whole lesson.

Down: Warmth With Questions Attached

Down — the fluffy under-layer of feathers from ducks and geese — is still one of the best insulators we know, gram for gram. Even if you live somewhere hot like Dubai, you've probably got a puffer jacket for winter travel, freezing classrooms, or a trip to Ski Dubai. Almost all of that fluff comes from birds.

The welfare concerns are real. Most down is a by-product of the meat industry, but two practices trouble campaigners most: live-plucking, where feathers are pulled from birds that are still alive, and force-feeding, used on some farms that also produce foie gras, a fattened-liver dish. Neither is universal — but without checks, a shopper has no way to tell which jacket came from where.

That's exactly why the Responsible Down Standard (RDS) exists. It bans both practices and follows the down through every step from farm to finished jacket — a system called chain of custody. The outdoor brand The North Face helped launch it in 2014, and a stricter cousin, the Global Traceable Down Standard, digs even deeper into parent farms.

So the takeaway isn't 'down is evil' or 'down is fine'. Down is a gradient — with a checkable standard marking the better end.

Silk, Peace Silk, and the Recycled Wildcard

Here's the fact that surprises most people: conventional silk is made by boiling silkworm cocoons with the pupa still inside, because letting the moth chew its way out would snap the single long thread. It takes thousands of cocoons to make one kilogram of silk, so the numbers add up quickly.

The alternative is called peace silk, or Ahimsa silk — 'ahimsa' is a Sanskrit word meaning non-violence. Developed in India, it waits for the moth to emerge naturally before the cocoon is spun. The trade-offs: the broken threads make a slightly rougher, pricier fabric, and there's no single global certification yet, so claims are harder to verify than RWS or RDS.

Meanwhile, the quiet overachiever of this lesson is recycled wool. The town of Prato in Italy has been shredding old wool garments and re-spinning them into new fabric for well over a century. No new sheep, no new farming impacts, and the fibre keeps its warmth. The Global Recycled Standard (GRS), also run by Textile Exchange, certifies it.

Notice what keeps happening: every fibre sits on a slider, not a switch. Your job isn't to memorise verdicts — it's to know which questions to ask.

Your Screenshot-This Cheat-Sheet

Time to make this practical. Screenshot this list — it fits on one phone screen:

- RWS (Responsible Wool Standard): no mulesing, plus animal welfare and land checks - 'Mulesing-free': a narrower claim, but specific and checkable - RDS (Responsible Down Standard): no live-plucking, no force-feeding, tracked farm to jacket - Global Traceable Down Standard: like RDS, stricter on parent farms - Peace / Ahimsa silk: the moth emerges before the cocoon is processed (no unified certification yet — ask the brand directly) - GRS (Global Recycled Standard): certifies recycled wool and other recycled fibres

Next time you're shopping — Dubai Mall, a thrift store, online — flip to the label and hunt for these names. If a brand claims 'ethical wool' with no standard behind it, that's your cue to ask. Brands answer messages from customers more often than you'd expect, and 'Is your down RDS-certified?' is a devastatingly good question coming from a teenager.

If you use the Rewoven app, this is exactly what the Animal Welfare grade summarises — whether a brand backs its claims with standards like these. You don't have to be perfect. You just have to be the person who knows the difference between a promise and a proof.
