"What Our Gearhead® Experts Are Saying:""I wore these on a late-season alpine hike where the temperature dropped fast and the trail got wet, and they handled everything without a problem. The Omni-Heat Infinity lining is noticeably warmer than a standard softshell, and the Omni-Shield treatment kept light rain and mud from soaking in. The gaiter clips and reinforced boot openings are exactly what you want when the terrain gets serious.""Late-season trails and cold-weather objectives demand legwear that keeps up when conditions turn rough, and the Columbia Vast Canyon Omni-Heat Infinity Softshell Pant is engineered for exactly those moments. Built on Columbia's Titanium platform for high-performance outdoor activity, these hiking pants combine advanced thermal retention with flexible, weather-resistant construction that holds up through long days in cold, wet, and demanding terrain. Omni-Heat Infinity lining uses an expanded pattern of thermal-reflective gold dots to retain body heat and push warmth back toward the skin, delivering Columbia's most advanced reflective technology in a pant built for sustained cold-weather output. Omni-Shield treatment repels moisture and resists stains at the fabric level, keeping the face fabric clean and fast-drying when conditions get messy. A gusseted construction and active fit allow natural movement on technical terrain, while integrated belt loops, a partial elastic waist, and reinforced boot openings with gaiter clips keep everything dialed from the ridge to the trailhead."
