Flash-Storm Protection

Named "Top Pick for Winter 2015" by Outdoor Gear Lab and "Best Waterproof Running Jacket" by Runner's World, the Outdoor Research Helium II Jacket is built to keep you dry through every mid-route downpour. The waterproof and super-breathable Pertex Shield fabric is highly compressible, packing down to the size of a granola bar. And since it weighs just 6.4 ounces, this is one piece you’ll never have to leave behind.

Note: At checkout, choose the Men's Helium II Jacket in aloe/charcoal, coyote, ember/charcoal, fatigue/ember, or peacock/jops (available in S–XXL); or the Women's Helium II Jacket in black/charcoal, black/flame, night/ultraviolet, pewter/rio, or ultraviolet (available in XS–XL).

Minimalist Design

Fully seam-taped with an adjustable hood, the Helium II features a YKK AquaGuard center-front zipper, a zippered Napoleon pocket, and an internal pocket that doubles as a stuff sack. Rounded out with elastic cuffs, a drawcord hem, and a carabiner loop, it’s cut wide enough for layers and long enough to tuck into your waistband, so you can head out prepared no matter the forecast.
