What Our Gearhead(R) 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.
