What Our Gearhead® Experts Are Saying: "These pants feel like true expedition gear. The new ePE GORE-TEX Pro membrane is just as bomber as the old version, but with a lighter environmental footprint. I love the high waist for harness compatibility and the full-length side zips for venting. The Cordura reinforcements are key—I don’t have to worry about crampons tearing them up." We count on the Millet Trilogy Icon GTX Pro Pant when alpine objectives demand uncompromising weather protection and durability. Built with a PFAS-free GORE-TEX Pro ePE 3L shell, these pants deliver waterproof, breathable performance while reducing environmental impact. Reinforced with Cordura® at the cuffs, they’re engineered to withstand crampons, sharp rock, and technical mountaineering use. Designed with the input of Chamonix guides, the Trilogy Icon prioritizes mobility and function. An adjustable waistband with a raised back panel keeps coverage secure under a harness, while removable braces add stability for long pushes. Three-quarter side zips allow airflow during high-output climbs, and elasticated cuffs with hook-and-loop adjustments create a reliable seal over boots. From storm-battered ridgelines to technical ascents, these expedition-ready pants deliver the blend of protection, breathability, and freedom of movement that defines serious alpine gear.
