What Our Gearhead(R) Experts Are Saying:"These pants are my go-to when I know I'll be facing extreme cold. The Bavarian wool insulation is warm but still breathable, and the stretch panels behind the knees and at the ankles keep them comfortable when I'm moving hard. The Dyneema reinforcement is a game-changer-it's light but seriously tough against crampons and rock."The Trilogy Jorasses Wool Pant is built for the most demanding alpine expeditions where dependable warmth and freedom of movement are essential. Millet engineered these technical pants with Bavarian wool insulation, offering an optimal warmth-to-weight ratio that performs in frigid conditions. Reinforced with Dyneema Ultralight fabric, they resist tearing and abrasion while maintaining impressively low weight. A hybrid construction ensures comfort and mobility: insulated panels provide critical warmth, while stretch zones behind the knees and at the ankles reduce bulk and prevent friction with mountaineering boots. Preformed knees enhance natural movement during climbs, and a stretch waistband ensures a secure, comfortable fit. As part of Millet's Trilogy Alpine Kit, these wool-insulated pants are purpose-built for extreme cold, high-altitude expeditions, and technical alpine pursuits where reliability and efficiency make all the difference.
