Made with soft, breathable fabric the Sea to Summit Face Mask is a comfortable, washable and reusable barrier against the transmission of airborne droplets. Comfortable by design, this mask provides full nose and mouth coverage and the elasticized ear loops keep the mask securely in place. The mask is made with brushed and quilted 50D polyester stretch-knit fabric that is thermoformed and seamless for a snug, contoured fit. Highly breathable and weighing only .35oz / 10g, this mask feels light on your face and is equally comfortable to wear for short trips to the store or longer commutes and extended travel. To re-use, simply machine wash at 140°F / 60°C and dry.
