The Aero Hat is a fitted performance hat built for high-output cold-weather activities including ski touring, cross-country skiing, winter running, and hiking. It uses Polartec® Power Air™ Active fabric, an updated construction that traps filament fibers in small pockets to drastically reduce microfiber shedding compared to standard fleece. The fabric offers four-way stretch, improved softness, faster drying, and better warmth-to-weight ratio than its predecessor, and is made from recycled materials that are themselves fully recyclable. Its low-profile fit also works well under a helmet.
Polartec® Power Air™ Active fabric sheds 80% fewer microfibers than conventional fleece
