Looking for a black mask with a subtle design? We've got you covered (get it?) and in our black+gray tie dye. This mask is a 2-layer fabric design with an internal pocket slit which could hold a filter -- fits comfortably over nose to stay put. The outer layer is woven polyester fabric while the inner layer is knit performance fabric. Fits slightly on the smaller side so if you're looking for something larger, check out our other mask.
