"What Our Gearhead® Experts Are Saying:""This jacket is made for high-output missions—it breathes better than any insulated piece I’ve used. The stretch fabric feels like a midlayer, but it still gives enough warmth for chilly starts. I throw it under a shell on storm days or wear it solo when I’m skinning hard.""The Nano-Air Ultralight Freeride Jacket is built for moving fast in the mountains. Patagonia designed this piece with a recycled nylon stretch ripstop shell bonded to a circular-knit backer, offering weather resistance with a soft, breathable feel. The lower body uses stretchy, air-permeable recycled polyester with a PFAS-free DWR finish, allowing airflow to keep us comfortable during high-output climbs and tours. Inside, 20g FullRange insulation—made from 100% recycled polyester—provides just enough warmth without sacrificing packability or mobility. A regular fit layers smoothly, while bluesign-approved and Fair Trade Certified construction ensures responsible production. Whether layered under a shell or worn on its own, the Nano-Air Ultralight Freeride is a versatile tool for freeriders who demand lightweight performance and comfort."
