This multi-layer, reusable and washable cloth face mask protects the wearer and people around. Amazing performance: this mask offers the perfect balance between breathability and safety. After 20 machine washes at 140° F, our fabric still offers almost twice as much breathability as what is recommended by health protection agencies and stops 98% of particles bigger than 3 microns (saliva droplets are between 5 microns and 10 microns in diameter). Up to four hours of protection. Not intended for medical use. Tri-fold offers great coverage. Two elastic earloops for maximum comfort. Removable, adjustable wire nose piece.
