The perfect solid colored face mask. Great for guys or gals who don't want any fancy designs and patterns. There is a pocket for you to add a PM2.5 filter into the front of the mask if you so choose. This is optional. We have included ONE free PM2.5 filters with each mask order. Straps are adjustable. Please hand-wash (or gentle cycle) with gentle detergent, and air dry. There is a bendable nose piece across the bridge of the nose. Fold/form it for a perfect fit across your nose!
