Outdoor Research Men's Helium II Jacket, Black/Hydro, Large

100% Waterproof, breathable and incredibly light, the Helium II Jacket provides super-lightweight, super-packable weather insurance. "This jacket is so dialed in and stripped down to the essentials for staying dry. Super lightweight. No other brand even comes close."-Outdoor Research Customer Review Built for flash-storm protection, the Helium II is 6% lighter and 10% more breathable than its predecessor. An ultra-compressible piece you'll never leave behind, it's so light and packs down so small, you'll forget it's clipped to your harness until you throw it on to ward off a sudden mid-route downpour. Compressible to the size of a granola bar and weighing just 6.4 ounces, this completely waterproof jacket doesn't waste any space in your pack.
