[AIRWAVE - MORE AIR.MORE WEAR. ] The large surface area of the patented wave design means more cooler air flows into the N95 respirator mask, for easier breathing and more comfort. [UNIQUE FLEXFIT DESIGN] moves easily with your face and stays in place. [PINCH FREE] Soft Foam Nose Cushion helps to maintain the seal without pressure points and there's no metal nose band to adjust. [ADJUSTABLE AND HANGEABLE CLOTH SMARTSTRAP] allows mask to hang down around the users neck to store when not in use, preventing premature disposal, reducing usage, less waste and saving money. [LASTS LONGER LESS WASTE] Exclusive DURA-MESH SHELL protects the filter media, so it stays cleaner-looking longer. The shell also resists collapsing in heat and humidity, the respirator holds its shape longer and the result is fewer respirators used.
