Cotton

Nope! When cared for correctly, your cotton period underwear stays fresh and breathable through every wear. Each pair is made with a bio-based finish that helps balance moisture and bacteria while reducing odor buildup through airflow. Our bladder leak underwear and period styles share the same lightweight gusset technology, keeping you dry through workouts or long commutes. The fabrics flex naturally with your body, staying soft and comfortable from morning movement to evening rest.

Air drying is the best way to keep your underwear soft and long-lasting. After wearing, submerge your pair in cold water to release buildup and preserve absorbency. Wash gently by hand or machine on cold using mild soap inside a Saalt Mesh Laundry Bag for delicate, lace styles. Avoid bleach, fabric softeners, and heat from irons or dryers, as these can affect elasticity and damage the gusset. Then, hang your breathable cotton period panties to keep fibers supple while extending their life.

That depends! Many find comfort wearing our cotton menstrual underwear from morning until bedtime. Wear time varies based on absorbency level and activity, but the gusset holds several pads’ worth of flow to keep you dry and supported. For heavier cycles, pair your underwear with a Saalt Cup or Saalt Disc for extended protection. The dynamic duo keeps you confident through workdays, errands, and recovery days without the discomfort of disposable products.

No, we never use any PFAS in our fabrics or finishes. Every textile meets strict global safety standards and is tested for known hazardous substances.
