Ventilation around the mouth and nose of the neoprene face masks help increase breathability. The face masks fit most and come with a hook and loop closure for a secure fit. Whether you are involved in skiing, biking, paintballing, and/or any other outdoor activity, Neoprene Half Face Mask is a must-have addition to your outdoor gear collection!
