Patagonia Nano-Air Ultralight Full Zip Hoody (Women's)

Patagonia’s Nano-Air Ultralight Hoody is made for those who go hard when the weather cools off. Built for high-output missions—think alpine starts, snowy ascents, or frosty trail runs—this ultralight layer brings the heat without trapping it.

It’s loaded with featherlight FullRange® insulation that stretches, breathes, and warms where it counts—across the hood, shoulders, chest, and back. Meanwhile, breathable underarm panels dump excess heat so you can keep charging without overheating. The shell and lining? 100% recycled polyester ripstop that moves with you, shrugs off abrasion, and is finished with a PFAS-free DWR to handle light drizzle and snow without blinking.

The fit is technical—streamlined for harnesses and backpacks, with articulated patterning that moves as hard as you do. The Light Touch Expansion Hood slips on even when zipped up and fits with or without a helmet, and the full front zip features a soft zipper garage at the chin for comfort on the move.

Need to stash it? The whole jacket stuffs into its own chest pocket with a carabiner loop, so you can clip it and go. Bonus points: stretchy Capilene® Cool cuffs wick moisture and let you push your sleeves up without a fight.

Weighs in at just 215 g, sewn in a Fair Trade Certified™ factory in Vietnam. Light, fast, and made to move—this hoody punches way above its weight class.
