"What Our Gearhead® Experts Are Saying:""I stuffed the Airshed Pro into the back neck pocket at the trailhead and forgot it was there until the ridge got cold and windy. It pulled on in seconds, the fitted hood replaced my hat entirely, and the extended sleeves covered my hands so I never had to stop for gloves.""Mountain running demands gear that earns its weight or gets left behind, and the Patagonia Airshed Pro Pullover earns every one of its four ounces. Built as part of an integrated running system, this ultralight wind shirt packs into its own back neck pocket so it disappears into the kit until the exposure picks up and you need it. The nylon shell cuts wind and sheds light moisture with a DWR finish, while remaining breathable enough to wear at full effort without turning into a sauna. Capilene Cool Lightweight fabric in the hood and sleeves manages moisture and moves with the body during dynamic efforts, while the slim-fit hood sits low and secure enough to stand in for a hat on cold ridgelines. Extended sleeves stretch over the hands when the wind bites and gloves feel like overkill to carry. For runners and fast hikers who build their kit around weight savings and versatility, the Airshed Pro Pullover covers the gap between base layer and hardshell without adding meaningful bulk or weight to the load."
