Patagonia M10 Storm Pant - Men's

Ultralight alpine protection and mobility in the M10 Storm Pant for technical ascents

What Our Gearhead® Experts Are Saying:

"I use these pants when weight, mobility, and weather protection all matter equally. The slim cut stays out of the way on steep ice, and the stretch where it counts makes high steps feel natural. They disappear under a harness but still block wind and wet snow better than most alpine shells I’ve worn."

We trust the M10 Storm Pant when objectives demand precision, efficiency, and total focus. Patagonia built these pants for technical climbing and mountaineering, where every movement matters and weather protection can’t come with excess bulk. From long approaches to committing pitches of ice, they move with us as naturally as our softshells while standing up to true alpine conditions.

The 3-layer H2No membrane delivers dependable hardshell protection while efficiently releasing heat during sustained efforts. A four-point gusset and articulated knees allow unrestricted movement on high steps and delicate placements, and the elastic waistband sits comfortably beneath a harness. Thoughtful details like a harness-accessible thigh pocket and elasticated cuffs that integrate cleanly with alpine boots make these pants feel purpose-built for serious mountain days.
