What Our Gearhead® Experts Are Saying:"I use these for winter trail runs and cold-weather touring days. The insulated panels at the seat and knees make a noticeable difference when it’s frigid, but the rest of the fabric breathes well so I don’t overheat on climbs. The slim fit layers easily under shells, and the stretch keeps my stride totally unrestricted."When frosty air settles over the trail and snow crunches underfoot, we pull on the Kor Alloy Tight from Mountain Hardwear to keep our stride strong. Built for winter miles and midseason touring, these insulated tights balance warmth and mobility so we can push through cold starts and shaded switchbacks.Pertex Quantum Air panels at the knees and seat block wind and resist light moisture, while 40g Primaloft Gold Active insulation traps heat right where we need it most. AirMesh lining enhances breathability to prevent overheating during hard efforts, and stretch woven fabric moves naturally with every climb and descent. An elastic waistband with drawcord secures the fit, and zippered hand pockets stash small essentials. Slim and streamlined, they layer comfortably under bibs or shells for versatile cold-weather performance.
