Cora Period Underwear
Organic-cotton-topped period underwear with a synthetic leakproof core, third-party tested free of detectable PFAS. A named PFAS-standard alternative, not a plastic-free product.
The verdict: Mostly plastic
Period underwear can't be plastic-free - the absorbent and leakproof layers are synthetic by necessity. Cora tops an organic cotton outer over a four-layer core that's about 91% polyester / 9% elastane plus a TPE leakproof layer, so plastic is central to the function. What earns it a place is chemistry: the fabrics are OEKO-TEX certified and additionally third-party lab tested to show no detectable PFAS/PFOA or azo dyes. It's here as a named PFAS- tested alternative, documented rather than recommended as plastic-free.

Reusable period underwear worn in place of pads or tampons, with a soft organic cotton outer and a four-layer absorbent gusset built into the crotch. Machine washable and reusable across many cycles. For readers weighing reusable options, the plastic-free community often prefers organic-cotton cloth pads plus a menstrual cup over any period underwear; Cora is the pick if you want the underwear format with published PFAS testing.
