Air Trim Sport (Sport + Racing) 1 Mask

Heavy breathing in cold temperatures or low humidity (desert climates or high altitude) can be uncomfortable or damaging to your airways. The AirTrim Mask is designed to recover heat and moisture from exhaled air - protecting your air passages from the cold and dry. This AirTrim Sport mask is the recommended starting pack for AirTrim cold weather masks. It comes with a Racing1 and a Sport filter, giving you the two most common filters you need for warming up and light training. Instead of wearing a buff or scarf over your face and nose, switch to a much more comfortable AirTrim mask.
