The Outdoor Research Men's Helium Down Jacket provides the lightweight packable warmth of down insulation with water-resistant fabrication to deliver better weather protection than traditional insulated jackets. The body of the jacket is constructed of an ultra-lightweight wind- and water-resistant 10D Pertex Quantum nylon fabric. Warmth is provided by high-performance ethically-sourced 800+ fill power down insulation. Renowned for their compressible properties and efficiency in providing warmth the feathers and fibers of down have an incredibly soft comfortable feel and continue to provide the best warmth-to-weight ratio of any insulation available. Due to the high loft and compressibility of down the jacket can even be packed into its own pocket and easily stowed in a pack. Other features include a full-length front zipper bound cuffs a drawcord-adjustable hem dual internal stash pockets a zippered chest pocket and zippered hand pockets with brushed tricot linings. Available in your choice of size and color options the Outdoor Research Men's Helium Down Jacket has a standard fit that balances thermal efficiency with the expectation that you'll be wearing other layers underneath the jacket. It also allows you to comfortably wear a hard shell over top.
