The best-selling and award-winning Helium Collection is even bigger, and lighter with the addition of the Helium Wind Hoodie. Featured in Backpacker Magazines 2021 Gear Guide among top trail-tested products, this wind shell is powered by the same durable lightweight Diamond Fuse technology that youll find in Ourdoor Researchs Down and Rain gear, reimagined to take on gusty runs, climbs, bike rides, and anywhere else youd encounter a headwind. Complementing the super strong Diamond Fuse exterior, the Helium Wind Hoodie sports a hidden interior mesh venting at the waist to dump built-up heat. The Womens Helium Wind Hoodie uses our beloved Krypta stretch woven fabric at the hip, complete with stretchy secure pockets, for a close fit that stays put even as you move fast with your phone or GPS device tucked away.
