Helium Rain Jacket - Men's

What Our Gearhead® Experts Are Saying:

"The Helium Rain Jacket basically lives at the bottom of my pack from early spring through late fall because at six ounces, I genuinely never notice it's there until I need it. The Pertex Shield Diamond Fuse construction is surprisingly capable for something this light, and the fact that it stuffs into its own chest pocket means I can clip it to my pack on approach and have it ready to pull on in seconds when a storm rolls in faster than the forecast suggested."

The forecast said partly cloudy, and the summit said otherwise. That is the exact scenario the Outdoor Research Helium Rain Jacket was built for, sitting quietly at the bottom of your pack at just 6.2 ounces until the moment you actually need it, then coming out fast and going on faster. It is not the jacket for standing in a downpour all day, but for the surprise shower, the windswept ridgeline, and the drizzly descent, it is hard to beat.

Outdoor Research built the Helium around Pertex Shield Diamond Fuse 2.5-layer construction, a bluesign-approved fabric that delivers waterproof and windproof protection in one of the lightest and most packable shells available at any price point. Fully sealed seams close off any gaps in the weather protection, a fixed, adjustable hood cinches down when conditions get serious, and reflective details at the logo and forearm keep you visible in low-light conditions on early starts and late finishes. The zippered chest pocket swallows the entire jacket when you need to stash it, and a carabiner loop and key clip let you keep it accessible outside the pack when the weather looks uncertain. For thru-hikers, trail runners, and anyone who refuses to get caught without a shell, the Helium Rain Jacket earns its six ounces every single time out.
