Built for mountain weather that changes faster than your mood, this Men's Helium Rain Jacket combines serious waterproof protection with a featherweight feel. Diamond Fuse technology keeps the fabric tough through countless adventures and washings, while taped seams and a YKK® AquaGuard® zipper seal out every drop. Breathable and windproof, it won't trap you in a sauna when the sun peeks back out. The genius part? It collapses into its own chest pocket, turning into a compact bundle that laughs in the face of pack space limitations. Reflective details keep you visible, adjustable cuffs and hood dial in your fit, and a carabiner loop means you'll always know where to find it. Whether you're pedaling through a surprise storm or summiting in sketchy conditions, this jacket proves that staying dry doesn't mean sacrificing comfort or style.
