Category: Period Underwear

The Saalt Leakproof Cotton Brief brings together everyday comfort and serious period protection in a mid-rise, full-coverage brief built for real wear. The body fabric is 95% cotton with 5% elastane, so it breathes and moves without binding, while the gusset lining uses 92% recycled polyester and is free from PFAS treatments. Every fiber meets Standard 100 OEKO-TEX certification, giving you clear ingredient transparency from the inside out.

  • Super absorbency holds the equivalent of 6 or more pads or 8 or more tampons, making it a reliable standalone for heavier flow days or a confident backup to a cup or disc.
  • Body fabric is made from biodegradable natural cotton fiber, offering breathability and a soft, familiar feel across up to 12 hours of wear.
  • Machine washable and true to size, so it fits into a low-waste routine without extra effort or guesswork.

Whether you are replacing single-use products entirely or simplifying what you reach for each month, this period underwear is designed to hold up wash after wash without compromise.

Evelyn E. ★★★★★

I put these on during my heaviest day and was impressed—the gusset absorbed well without any dampness, and the cotton blend felt soft against my skin. They fit true to size and held up fine after several washes.

Chloe S. ★★★★★

Wearing these through my heaviest day without any leaks was a relief—the 95% cotton fabric breathes better than the synthetic pairs I tried before. The mid-rise waistband stays comfortably in place without digging in.

George O. ★★★★★

The full-coverage cut stays put even during my heaviest night, and the cotton feels breathable all day long. It’s been a game-changer for my cycle, with zero leaks or discomfort.
