Millet Trilogy Icon LT Down HD Men's Down Jacket

Designed for mountaineering, the MILLET Trilogy Icon LT Down HD men’s down jacket is aimed at demanding climbers seeking high-performance thermal protection in winter conditions. Lightweight and packable, it’s ideal for outings where weight savings and minimal bulk in the pack are crucial. Its water-repellent treated goose down filling provides effective insulation with minimal bulk. The sporty, modern cut promotes freedom of movement both on the rock face and during the approach. This down jacket thus integrates easily into a layering system for mountaineering trips during the WINTER 2027 season.

K DRY™ goose down insulation for optimized thermal performance in mountaineering

The Millet Trilogy Icon LT Down HD men’s down jacket prioritizes insulation with a 90/10 K DRY™ goose down fill rated at 800 cuin, known for its excellent loft and ability to trap air. With a down weight of 115 g, this construction aims for optimized thermal insulation for alpine activities while keeping the total weight limited to 390 g. The specific water-repellent treatment of K DRY™ down helps maintain insulation efficiency in moderately wet conditions during mountaineering use. This combination of loft, lightness, and water-repellent treatment meets the needs of users seeking a technical down jacket for ascents and mixed-terrain routes.

A lightweight and durable outer shell for demanding use

The 39 g/m² 100% polyamide outer fabric combines lightness and durability, two key criteria for mountaineering apparel subjected to friction and repeated handling. Its construction enhances the jacket’s overall packability, allowing it to be easily stowed in the included stuff sack—a practical feature for optimizing organization in your pack. The PFC-free DWR (Durable Water Repellent) treatment on this outer shell is designed to provide surface protection against moisture while adhering to a PFC-free approach. This choice of materials and finish contributes to the garment’s durability during regular mountain outings.

Sporty fit and features designed for mountaineering

The sporty and modern cut of the Trilogy Icon LT Down HD men’s down jacket is designed to follow the body’s movements during ascents and rope handling, without adding excess bulk. The front opening with a two-way zipper allows you to adjust ventilation and access gear depending on the situation, while remaining compatible with a climbing harness. The helmet-compatible hood meets the demands of technical mountaineering, providing additional head protection while leaving enough room for gear. The elastic drawcord at the waist helps block cold air and keeps the jacket secure on the torso while moving.

Technical details designed for the field

The two zippered hand pockets, designed to be compatible with a climbing harness, are positioned to remain accessible even when you’re roped up or wearing a harness, making it easy to store small items you’ll need on the rock face or during the approach. The included stuff sack allows you to compress the jacket and pack it compactly in a mountaineering backpack, keeping it protected and ready to slip on during breaks or when conditions change. The combination of a total weight of 390 g, carefully selected materials, and these functional details makes this model a technical piece suited for alpine outings where optimizing volume and organization remains a key criterion.

The MILLET Trilogy Icon LT Down HD men’s down jacket is thus a lightweight, compressible jacket designed for mountaineering, combining K DRY™ 90/10 800 cuin goose down, a durable polyamide shell, and features compatible with wearing a harness and helmet.
