Handmade in Honolulu, Hawaiʻi. The Hīhīwai Mask, our third style of reusable face masks, helps to filter out dust, bacteria, smoke and pollen. This streamline design features a 100% Kona Cotton lining and a pocket for your carbon filter (not included). The Hīhīwai comes with extra elastic and is styled to compliment the shape of your face. This mask is constructed with self-bound edges for a fine finish and added durability for repetitive wear.
