Hanna Andersson Classic Organic Cotton Unders

Recommended

Durable, widely-available GOTS + OEKO-TEX organic cotton briefs - but 5% spandex is blended through the fabric, so slightly more synthetic than a 100%-cotton-body brief.

The verdict: Minimal plastic contact

GOTS-certified and OEKO-TEX Standard 100 tested organic cotton, with an encased elastic waistband and tag-free flatlock seams. The difference from the cleaner picks is that the fabric itself is 95% organic cotton / 5% spandex - the elastane is blended through the whole knit, not confined to the band - so it's a touch more synthetic. Minimal-contact, and the pick for durability and easy availability.
