When the sun sits high, and the trail offers no shade, this is the layer you reach for. The Ossa Half-Zip Hoodie keeps you covered without trapping heat, so you can keep moving through exposed ridgelines, alpine scrambles, and long summer approaches without slowing down to manage layers.

Stretch fabric moves with you on technical terrain and off trail routes without restriction UPF 50 plus nylon stretch ripstop blocks harsh sun while staying light and breathable
Half zip design lets you dump heat fast on steep climbs without stopping to change layers
StormHood™ adds full coverage for head and neck when sun exposure ramps up above treeline
Lightweight construction packs into its own pocket so it disappears in your pack when not in use
