Comfortably soft and breathable - the Houdini Airborn Hat! This beanie isnt just super lightweight, it also absorbs body moisture directly from the skin. This keeps your head nice and dry. The odor-neutralizing fibers allow you to wear the beanie for a long time without noticing an unpleasant odor. The anti-static material is made of Merino wool and silk, keeping your hair on your head, not on the beanie. The Airborn Hat regulates temperature whether its hot or cold. With its excellent wearing comfort, its perfect for ski touring, mountain biking, and jogging!
