What Our Gearhead® Experts Are Saying: "This fleece has been a perfect balance piece on long alpine trips. The X Loft fabric holds in warmth when I’m resting, but the Tecnostretch panels breathe well when I’m moving hard. I like that the chest pockets sit high so I can access them with a harness on—it really feels designed for mountaineering." The Trilogy Icon X Loft Jacket is built to carry us through multi-day alpine missions where both warmth and mobility matter. Millet used dual recycled Italian fabrics—Polartec Thermal Pro X Loft across the torso and shoulders for reliable insulation, and Tecnostretch panels where extra breathability and flexibility are needed. The result is a technical fleece that adapts seamlessly from steep ascents to chilly hut rests. The ACTIVE FIT keeps the cut streamlined for layering under shells, while elastic trims ensure the jacket stays in place during dynamic movement. High-set chest pockets, a Trilogy signature, remain accessible even under a harness or pack belt, while the protective collar offers wind-blocking coverage when conditions shift. Soft, breathable, and highly functional, the Icon X Loft Jacket is a versatile alpine midlayer designed to perform on demanding expeditions without weighing us down.
