One size fits most, this style features two soft cinching beads that allow for added fit adjust-ability. Our non-medical grade face masks are made with Stance’s premium Butter Blend fabric to maximize your comfort. Stance masks are washable and reversible (please clean between each wear). For each mask purchased, we will gift a pair of socks to medical frontline workers through our ‘Stance for Scrubs’ Initiative. Keep covered comfortably.
