The North Face Summit Breithorn Pant - Men's

Summit Breithorn Pant delivers ultralight alpine warmth for high-elevation missions

What Our Gearhead® Experts Are Saying:

"I use these as my go-to insulated layer for cold alpine starts and transitions. They’re impressively warm for how little they weigh, and the full-length side zips make them easy to pull on over boots and layers. The articulated knees keep them comfortable when moving, and they pack down small enough to always justify bringing along."

When the altitude climbs and temperatures drop, we trust the Summit Breithorn Pant to keep us warm without weighing us down. Built by The North Face as part of the Summit Series, these insulated pants are designed for cold, committing days in the mountains—whether we’re gearing up at a windy col or taking a break high above treeline.

Lofty 800-fill ProDown insulation traps serious warmth while maintaining a streamlined, low-bulk feel that moves easily with us. Pertex Y Fuse ripstop fabric resists abrasion and sheds light moisture, while reinforced overlays at the seat, knees, and cuffs add durability where it matters most. Full-length side zips and an elastic waist with drawcord make layering fast and efficient, and articulated knees let us move naturally when every step counts.
