Knix (Makers of Period Undies and Sports Bras) Have Face Masks — They're Great For Workouts!

Knix Freshfix Air Face Masks can be sanitized and reused over 50 times. Sanitization can be done in the microwave via steaming or by boiling in water. They can also be cleaned using a UV sterilization light or under high heat in the washing machine (that's what I did, and they wash really well!).
