The Aero Hat is built from Polartec® Power Air™ Active fabric, a structural fleece that traps filament fibers within the weave to drastically reduce microfiber shedding during wear and washing. Designed for high-output cold-weather activities like ski touring, winter running, and cross-country skiing, it delivers a strong warmth-to-weight ratio with a fitted, four-way stretch construction that sits comfortably under a helmet. The fabric is made from recycled materials and is fully recyclable at end of life, supporting a closed-loop material cycle.
