Brands I've checked, one by one

GOTS licence GOTS-25565

Kite have a proper GOTS-certified organic cotton range, but they also stock items in bamboo viscose and other blends — so I flag the GOTS items rather than the whole brand. The kids' range in particular has lovely classic British prints (puffins, foxes) on certified organic cotton. Just check the label.

Founded by an illustrator, and it shows — the prints are some of the boldest in the organic kids' space. Whole range is GOTS-certified organic cotton. Made for actual play: my test for kids' clothing is whether it survives knees-in-mud, and Toby Tiger does.

Komodo have been doing ethical fashion since 1988, which is longer than most. GOTS organic cotton and Fair Wear membership on flagged items — but they also do EcoVero viscose and some blends, so it's not range-wide. Excellent for grown-up cuts; one of the few ethical brands that doesn't only make t-shirts.

Greenfibres is a retailer, not a brand — they carry Living Crafts. Only the products under their '100% organic cotton' underwear filters qualify (they also stock 95/5 and 92/8 blends elsewhere). The trick with the underwear: the elastic is wrapped inside organic cotton so only cotton touches skin — no elastane percentage on the label. Rare and honest.

Welsh outdoor brand that's been doing organic cotton, hemp and merino since 1995 — long before it was fashionable. Built to last decades, not seasons. The hemp tees in particular are some of the toughest natural-fibre garments I've handled.

100% organic cotton — entire range

Built specifically for eczema and sensitive-skin sufferers — 100% organic cotton, no synthetic stitching, no dyes that haven't been tested for skin reactivity. If you've got an Ovine sensitivity profile set to eczema or baby, this is one of the very few brands that grades A+ across the whole range.

Plant-fibre, fully compostable — entire range

An actual zero-waste bra — Tencel, organic cotton, natural rubber, even the thread and labels are plant-based. Cut it up at end of life and it composts. There's nothing else like this on the market; most 'sustainable' lingerie still has elastane or polyester somewhere.

One of the UK's biggest GOTS-certified organic clothing brands — they've held the cert since the start, and it covers their whole kids' range. Cornish-designed, built for actual children rolling around in mud. A staple of our catalogue.

GOTS organic cotton and TENCEL across most of the range, but they also run a recycled-nylon activewear line — so it's flagged item by item rather than range-wide. Their organic cotton basics are some of the best-cut underwear on the market.

GOTS licence SC-017097-0, issued by IDFL Laboratory and Institute Inc.

Cottonique's organic-cotton range is covered by a verified GOTS scope certificate (SC-017097-0, IDFL, valid to Nov 2026) — I've checked the licence on the GOTS public database. That's a brand scope certificate covering their range, not a separate per-SKU licence per item. The strictest brand I've found for sensitive-skin and allergy sufferers: absolutely no spandex, elastane or latex in the fabric or bands — the elastic in the waistbands is encased cotton-thread loops rather than rubber. Honest caveat: the optional removable pads in some bras use lightweight polyurethane foam, which they disclose clearly (same approach as The Very Good Bra). If you've got an Ovine sensitivity profile set to eczema, latex allergy or chemical sensitivity, this is one of the only brands that grades A+ across underwear, sportswear and sleepwear.

GOTS licence 256894

Q for Quinn is a GOTS-certified company (Ecocert Greenlife, Licence #256894), which means the certification covers the brand itself, not just individual styles. The bulk of the range is 95–100% organic cotton: socks sit at 97–98% with a small spandex/nylon content for fit and durability (industry-standard for any sock that stays up), underwear and bras are 95–100% organic cotton with ~5% elastane for stretch where needed, and a growing 'Natural / Pure' line is 100% undyed organic cotton with no synthetic stretch at all. Honest caveats: the stretch styles aren't elastane-free, so if you need a fully spandex-free piece pick from the Natural 100% range or the Cottonique catalogue instead. Latex-free across the range, and they're publicly working toward fully biodegradable garments. A strong fit for sensory and sensitive-skin kids — their kids' socks and underwear are some of the most-reviewed in this category.

British wool — entire range

Bedding, not clothing — but worth flagging here because so much 'wool' bedding is actually polyester with a wool top layer. The Wool Room source from named British farms and tell you the breed. If you're trying to get synthetic out of the bedroom too, start here.

Solves the school uniform problem. Standard supermarket polos and trousers are typically 100% polyester — Eco Outfitters' whole range is GOTS organic cotton in the same shapes and colours schools require. Costs more per item but lasts multiple terms.

Danish family business going since 1916. Whole range is GOTS organic cotton or pure merino — underwear, socks, base layers for the whole family. The thing that sets them apart is the fit on plus sizes and tall sizes, which most organic-basics brands neglect.

Conservationist Chris Packham's print store — every tee is certified organic cotton, printed in a renewable-energy factory in the UK, and proceeds go back into wildlife work. The designs are gorgeous and it's a rare case of celebrity merch that actually meets the cert bar.

British family-run, GOTS + Soil Association certified across the whole range. Specialises in baby muslins, sleepsuits and basics. The double GOTS + Soil Association cert is unusual and means they pass both EU and UK organic audits independently.

DUNS have been at this since 2007 with three rules: organic materials, unisex designs, distinctive prints. Whole range is GOTS organic cotton. A favourite of mine for hand-me-downs because the unisex cuts genuinely work across siblings.

Piccalilly only use GOTS-certified organic cotton — and specifically Chetna cotton, which is grown by a farming cooperative in India that the brand has worked with directly for over a decade. It's the rare case where 'fairly traded' isn't a marketing line, it's the actual supply chain. Range-wide cert. Piccalilly's direct shop comes and goes; for now I link you to stockists rather than risk a broken product feed.

Disana have been making in Baden-Württemberg since 1982 — kbT (German organic-livestock standard) merino wool with no chemical additives, and GOTS organic cotton. No synthetics anywhere, no nylon reinforcements, no elastane. Their boiled-wool walker suits are a cult classic for a reason. Disana sell mainly via specialist stockists rather than a public direct shop, so I link you out to find them.

GOTS stated. No licence number on file, recorded as the brand's own statement.

Small UK brand, GOTS organic cotton across the whole range and a Fair Wear member — meaning the factory conditions are independently audited, not just the cotton. Plain, well-cut basics rather than statement prints. Sold through indie shops; I link out to stockists.

Didymos invented the modern woven baby wrap in 1972 and they still set the standard. Whole range is GOTS-certified organic cotton or natural blends (hemp, linen, wool) — no polyester carriers here. Wraps are sold via specialist babywearing stockists and consultants, so I point you to those rather than a SKU grid.

GOTS stated. No licence number on file, recorded as the brand's own statement.

Etta Loves' whole point is sensory prints designed with vision scientists to stimulate newborn eyesight — and they execute it on GOTS-certified organic cotton muslins. A rare case where the novelty (the prints) and the substance (the cert) both stack up. Mostly sold through indie baby shops.

Swedish family-run since 1989, doing reusable nappies, cotton wipes and period care on GOTS-certified organic cotton. One of the few reusable-nappy brands where the absorbent layers are organic cotton rather than bamboo viscose or microfibre. Distributed via cloth-nappy specialists.

GOTS stated. No licence number on file, recorded as the brand's own statement.

Spanish brand designing in Madrid, GOTS-certified organic cotton across the kids' range. Distribution in the UK is via independent kids' shops, so I link out to stockists rather than maintain a direct SKU list.

100% natural Hevea rubber — entire range

Bath toys and teethers are one of the worst hidden plastic categories — most are PVC or TPE filled with mouldy water. Oli & Carol's whole range is single-piece natural Hevea rubber, no seam for water to get into, fully biodegradable. The cleanest option in the category. Sold via baby and toy shops.

GOTS stated. No licence number on file, recorded as the brand's own statement.

Period care is mostly plastic and rayon, and the few 'organic' brands often still have a synthetic top sheet or back layer. Organyc is one of the only ones where the whole pad, liner or tampon is 100% GOTS-certified organic cotton — no plastic, no rayon, no chlorine bleach. Same goes for their baby cotton squares. Sold via health-food shops and pharmacies.

GOTS stated. No licence number on file, recorded as the brand's own statement.

Lunch bags are usually nylon or polyester with a PEVA lining — Fluf's whole range is GOTS-certified organic cotton instead, including the lining. Designed to wash and last years rather than be a single-season novelty. Sold via indie kitchen and kids' shops.

GOTS stated. No licence number on file, recorded as the brand's own statement.

Wrapping paper is largely non-recyclable thanks to foil, glitter and plastic coating. Fabrap make reusable fabric wraps from GOTS-certified organic cotton — the furoshiki idea, properly executed. One wrap replaces dozens of single-use sheets. Sold via gift and zero-waste shops.

One of the very few gym-focused brands making pieces that are genuinely single-fibre — 100% organic cotton or 100% merino wool, with no elastane blended in for stretch. Ryker publish a brand-level statement about GOTS-certified sourcing and OEKO-TEX partners but don't print a per-SKU licence number, so Faye admits only the single-fibre pieces where the fibre claim is explicit on the SKU page. Their two-fibre pieces (like the Apex Short with a cotton shell + wool liner) are held for review rather than admitted, so you know exactly what you're getting.

Alpkit are a UK outdoor brand and most of what they make is synthetic — nylon-polyester mountain shirts, softshells, membrane waterproofs. But hidden inside that range are the pieces that meaningfully close the outerwear gap: the Ranger Ventile jacket is double-layer 100% organic-cotton Ventile® woven in Switzerland from GOTS-certified cotton, with a PFAS-free (C0) DWR — genuine plastic-free weatherproof outerwear, which almost doesn't exist in the market. Their Kepler base layers are 100% merino (RWS-certified, no nylon reinforcement) and their Blank Canvas tees are GOTS organic cotton. Faye admits only those single-fibre SKUs and rejects the synthetic majority.

Plainandsimple are, honestly, the closest thing to a Tier 1 ideal for cotton basics. Their entire proposition — stated plainly across the site and on each PDP — is 100% GOTS-certified organic cotton, cotton stitching thread, cotton neck labels, and 0% plastic anywhere in the garment. That's the piece almost every other 'organic cotton' brand gets wrong: they'll use organic cotton fabric and then a polyester tag or polyester thread and quietly break the plastic-free claim. Plainandsimple don't. This is the brand to send someone who wants everyday tees, sweats and joggers without the elastane, without a synthetic tag scratching their neck, and without having to read a spec sheet. They previously had no underwear (the earlier rejection was scoped to that gap only), but for tops, sweats and joggers they're a near-total admit.

Peregrine make the case that heritage and honesty can coexist. Eight generations in the same English family since 1796, wool farmed sixty miles from the factory, and — genuinely rare in modern knitwear — a stated refusal to mix in acrylic or elastane. Their 100% British Wool Hudson Aran and 100% Merino jumpers and cardigans clear the strict rule cleanly. But this brand needs care: their cotton pieces use 'GOTS-certified dyes' which is NOT the same as a GOTS-certified garment, so cotton items are held out of Tier 1. Their waxed jackets are rejected for the same reason as Barbour — synthetic linings. Faye lists only the wool knitwear that genuinely qualifies.

Tiralahilacha is a small Spanish menswear label with an unusually clean position: their PDPs literally read '100% Organic Cotton GOTS Certified' and they state on-site that they steer clear of synthetic fibres. That directness is rare. The catch is stock — several of the strongest single-fibre SKUs I vetted were sold out at time of check, so Faye is holding them pending in-stock re-verification rather than listing dead links. Their 'Hugo' linen-blend shirts are honestly rejected: even the word 'blend' fails the strict rule.
