What Our Gearhead® Experts Are Saying:"These are my go-to cold-weather layering pants. The gridded fleece keeps me warm without overheating, and the windblock overlays make a big difference when I’m out in exposed terrain. Super comfy and breathable—they don’t hold me back on the move."Built for movement in rugged mountain weather, the Tribrid Pant blends warmth, mobility, and weather resistance in a thoughtfully mapped design. Gridded fleece insulation wraps us in breathable warmth, while durable woven windblock panels add protection right where we need it—on the knees, calves, and seat. Whether we're starting early on a skin track or layering under a shell for the lift ride down, these pants bring dialed performance to every cold-weather pursuit. The soft interior brushed fleece delivers thermal regulation without the bulk, and Japan-milled TREO fabric enhances stretch and durability in key areas. Details like TREO-lined handwarmer pockets, a zippered side stash pocket, and cuffed legs with articulated fit help these pants excel in alpine layering systems and basecamp lounging alike.
