Airtrim Cold Air Mask Racing Blue
Airtrim is a heat/moisture exchanger which recovers the heat and moisture from exhaled air. The filter heats the air you breathe in, protecting your air passages from the cold. Airtrim Cold Air Mask Racing includes the mask and one each of Racing 1, 2 & 3 filters.
During use the filter gets very damp, and you should clear it regularly by blowing vigorously through the mask. Avoid touching the wet filter as it tears easily. Allow the mask and filter to air dry.
Always bring along spare filters on long training sessions and mountain trips. Spare filters must be kept dry.
Filters that are adequately dried between uses should last 20-30+ sessions.
