Manufactured by Phunkshun Wear in Silverthorne, CO.
The lightest performance mask on the market.
The SL is constructed from a single layer of moisture wicking stretch polyester with an antimicrobial application to prevent odor from bacteria and sweat. A secure and stretchable three thread cover-stitch finishes off the top and bottom for a clean look and feel. UPF 50+ blocks 99% of all UV rays for protection from the sun without the greasy cream.
