Outdoor Research Helium UL Pant - Men's

Helium UL Pant delivers ultralight waterproof protection in a compact, fast-moving design

What Our Gearhead® Experts Are Saying:

"I always keep the Helium UL Pant in my pack for alpine days and thru-hikes. It weighs next to nothing, packs into its own pocket, and gives me full waterproof protection when the weather shifts. Super easy to layer over trail pants too."

When we're chasing big mileage or moving fast in alpine terrain, the Outdoor Research Helium UL Pant is our go-to storm shell. This ultralight pant offers reliable waterproof and windproof protection without the bulk, designed for summit pushes, thru-hikes, and anywhere pack space is at a premium.

Crafted with a 2.75-layer Toray shell and fully seam-taped for complete coverage, the Helium UL Pant features ankle zips for quick layering, an elastic waistband with gripper tape for secure fit, and a gusseted crotch for uninhibited movement. The entire pant packs into its own back pocket so it’s ready when the forecast changes—and forgotten when it doesn’t.
