Category: Period Underwear

The Saalt Leakproof Cotton Bikini brings together a low-rise, slightly cheeky cut with a body fabric of 95% cotton and 5% elastane, so it moves and breathes like underwear you already love. The gusset lining uses 92% recycled polyester, is free from PFAS treatments, and is built on OEKO-TEX Standard 100 certified fibers, giving you clear ingredient transparency from the outside in.

  • Super absorbency replaces 6 or more pads or 8 or more tampons, delivering up to 12 hours of leakproof protection without backup.
  • Biodegradable natural cotton body fabric sits against skin that needs breathability all day, reducing synthetic contact where it matters most.
  • Recycled polyester lining keeps the absorbent core circular-material conscious without compromising the slim, smooth silhouette under clothing.

Available in Super, Heavy, and Regular absorbency, the Leakproof Cotton Bikini fits into a straightforward period care routine whether you are managing a heavier flow or lighter days. Pick your absorbency, wear it with confidence, and leave the backup planning behind.

Customer Reviews (4.8 / 5 · 5 reviews)

Timothy ★★★★★

I was nervous about the fit, but the cotton blend breathes so well I forget I'm wearing period underwear. The gusset coverage is just right for my medium flow days, no bunching or shifting.

Nicholas M. ★★★★★

The low-rise waist sits perfectly under my jeans, and the cotton blend is so breathable I forget I'm wearing anything special. It holds up well through a full workday without any leaks or bunching.

Ella ★★★★★

The low-rise cut sits exactly where I want it, and the 5% elastane gives just enough stretch that I forget I'm wearing anything different. It's genuinely breathable for all-day wear, and the slightly cheeky fit is a nice bonus for something this practical.
