The triple-layer structure is made from two layers of breathable AIRism fabric plus a filter sandwiched between. The mask also features a UPF 40 rating, and comes in a 3-pack and three size options (S, M, L). The AIRism fabric is antimicrobial, self-deodorizing, heat-releasing, and sweat-absorbing. It’s machine-washable, so you don’t have to worry about any special instructions to keep it clean. The filter inside the mask will last up to 20 washes, so the pack of three will last you a good while. Right now, it comes in white and black, with a light gray launching in September.
