Modibodi Period Underwear
Period underwear with a wide choice of natural-fiber tops - organic cotton, merino, TENCEL - over a synthetic leakproof core, third-party tested PFAS-free. Named alternative to Saalt, not plastic-free.
The verdict: Mostly plastic
Like all period underwear, Modibodi's can't be plastic-free - the leakproof and absorbent layers are synthetic. What sets it apart is the range of natural-fiber outer options: GOTS organic cotton, merino wool, TENCEL, and bamboo viscose, over a gusset of polyester/polyamide/elastane (with a merino or "polybrush" absorbent option). Its fabrics are OEKO-TEX certified and third-party tested free of PFAS. It's documented here as a named PFAS-tested alternative, not recommended as a plastic-free product.

Reusable period underwear worn in place of pads or tampons, sold across many cuts (bikini, full brief, boyshort) and absorbency levels. Its distinguishing feature is outer-fabric choice: the same style comes in GOTS organic cotton, merino wool, TENCEL, or bamboo viscose. As with Cora, the plastic-free community often prefers reusable organic-cotton cloth pads plus a menstrual cup over period underwear; Modibodi is the pick if you want a natural-fiber top with published PFAS testing.
