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: Significant plastic contact
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.
What it's made of
| Part | Material | Skin contact |
|---|---|---|
| outer fabric organic cotton outer layer (95% cotton / 5% elastane outer shell) | Cotton | Yes primary |
| absorbent core four-layer absorbent gusset, approx. 91% polyester / 9% elastane | Polyester | Yes primary |
| leakproof layer TPE (thermoplastic elastomer) leakproof membrane | Plastic other / unspecified | Yes incidental |
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 was a strong pick for the underwear format with published PFAS testing until it discontinued the line.
