Millet TRILOGY ICON X LOF Men's Mountaineering Fleece

A men's mountaineering fleece designed as a mid-layer for mountain use

The Millet TRILOGY ICON X LOF men's mountaineering fleece is designed for mountain activities and offers thermal insulation, breathability, and freedom of movement. Its technical construction combines Polartec® fabrics to meet the demands of mountaineering and ski touring. Weighing just 340 g, it easily fits as a mid-layer in your mountain gear.

Dual Tech™ construction for freedom of movement

This fleece jacket features a Dual Tech™ stretch construction that combines Polartec® Thermal Pro® X Loft® and Polartec® Power Stretch® Pro™. This combination brings together warmth and flexibility in a single garment, supporting movement during ascents, on challenging terrain, or during sustained exertion. The fabric blend also incorporates recycled polyester in the Thermal Pro® X Loft® layer, as well as nylon and spandex in the Power Stretch® Pro™.

An ergonomic cut for a snug fit during mountaineering

The ergonomic, fitted cut follows the body’s contours to minimize bulk under another layer or a harness. The protective high collar provides extra coverage around the neck, while the elasticated cuffs and hem help keep the jacket in place during activity. Together, these features create a technical fleece suited for activities where the precision of the cut matters as much as comfort.

Details designed for use with a harness

The two zippered chest pockets are compatible with a harness, allowing for functional access even in a mountaineering setup. The inclusion of a two-way zipper reinforces this design philosophy by making it easy to adapt the jacket to the situation. These features position the Millet Trilogy Icon X Loft Men’s Fleece Jacket within an alpine context where accessibility and organization of gear remain essential.
