What Our Gearhead® Experts Are Saying:

"I bring the Helium Rain Jacket on every hike and trip—it’s so light I forget it’s there until I need it. The Pertex Shield fabric sheds rain and wind, and it stuffs into its pocket in seconds. A must-have for fast missions and unpredictable weather."

When we're chasing big miles or venturing out with a questionable forecast, we trust the Outdoor Research Helium Rain Jacket to keep us covered without slowing us down. Crafted with ultralight yet durable Pertex® Shield Diamond Fuse fabric, this jacket offers waterproof protection and breathability in a design that packs down to the size of an apple. It’s built for those who move fast and need their gear to keep up—without compromise.

Fully taped seams, elastic cuffs, and an adjustable hem seal out wind and water, while the bluesign®-approved materials offer a lighter footprint on the planet. It stashes easily into its own hand pocket, making it the piece we reach for when skies darken mid-ascent or when extra layers just aren't an option. For trail, travel, or everyday carry, the Helium is our dependable shield against the elements—always there when we need it, and invisible when we don’t.
