Feel fast and light in the Ossa 1/2 Zip Hoody. Built for summer hikes and high-exposure days, its athlete-inspired silhouette minimizes bulk without compromising on coverage. Breathable, UPF 50+ stretch nylon feels cool and light on your skin, while the integrated StormHood shields your head and neck. When temperatures peak, the half-zip allows for easy venting—no need to shed layers mid-hike.
