The MILLET TRILOGY JORASSES 3S GTX mountain boots are the choice for alpinists who prioritize lightweight performance, reliability, and comfort in extreme conditions. Designed for demanding climbs and low temperatures, the lightest model in its class effectively protects feet down to -10°C. The BOA® Fit System allows for micro-adjustment, ensuring a precise fit, stability, and performance in challenging terrain. The Vibram® outsole, with its specially designed construction, provides excellent grip on rocky and steep sections. The boots also offer exceptional comfort at high altitudes, thanks to their anatomical fit, cushioned sole, and soft ankle padding. An adjustable gaiter with a zipper and Velcro closure enhances functionality, while the durable Italian upper provides protection and abrasion resistance. These technical boots are built for serious mountain adventures—reliable from base to summit.
