Absolute Zero Pant - Men's

.What Our Gearhead® Experts Are Saying:

"I’ve relied on these in brutally cold, high-altitude conditions where stopping isn’t an option. The 800-fill down is incredibly warm, and the welded baffles help block wind and moisture. The reinforced seat and knees hold up against sharp rock, and the wraparound zip makes layering over boots surprisingly easy during transitions."

When the forecast turns severe and the objective pushes into true expedition territory, we trust the Absolute Zero Pant from Mountain Hardwear to keep us protected. Built alongside mountain guides and elite alpinists, these heavyweight insulated bib pants are engineered for the coldest, most unforgiving environments on earth.

Welded baffle construction locks in loft and helps resist moisture intrusion, while 800-fill RDS-certified Allied Down delivers exceptional heat retention with responsible sourcing. Reinforced Pertex panels at the seat and knees stand up to abrasive granite and shale on exposed ridgelines. An insulated bib adds core warmth and weather protection, and the wraparound zip entry simplifies layering over bulky boots and crampons. With multiple zippered pockets for essential tools and nutrition, these pants are purpose-built for high-altitude expeditions and extreme cold mountaineering.
