Straumnes is a breathable and lightweight jacket built for the needs of endurance athletes. In Iceland, “waiting for a nice day” often means “not training.” We worked with runners, cyclists, and fast hikers to design a jacket that balances the protection they need with the agility they demand - all to enable more time in nature. The core of Straumnes is a breathable shell fabric imbued with 4-way stretch. GORE-TEX Infinium technology provides weather resistance. Stretch panels support key movements. Reflective stripes on the sleeves keeps athletes safe, while two zippered hand pockets protect essentials. Finally, a sweat-wicking liner fabric ensures next-to-skin comfort. Straumnes fits snugly, but stretches and moves with the body in motion. Those between sizes should consider sizing up.
