Pact

A mainstream, affordable way into organic cotton: the fiber is genuinely GOTS organic and Fair Trade, which is more than most high-street brands offer. But Pact's standard underwear is about 95% cotton / 5% elastane, with the elastane in both the body and the non-roll waistband, so it rates minimal-contact, not plastic-free. It's the accessible, widely-stocked pick for people who want organic cotton without hunting for a specialty brand.
