The Outdoor Research Helium Down Jacket combines ultralight packability with rugged durability, using Pertex® Quantum Diamond Fuse Technology and 800+ fill power responsibly sourced down for serious warmth without the bulk. Pertex® Shield reinforced shoulders and upper sleeves add waterproof protection where you need it most, while the jacket stuffs into its own pocket for easy stowing.
