Designed for fast alpine movement, hiking, climbing, and high-altitude approaches, the POLARIS Men's Lightweight Alpine Performance Down Jacket delivers efficient warmth for cold conditions where every gram and every layer matters.

The movement-focused fit and articulated construction support active climbing and easy layering, while the low-bulk design stays comfortable beneath a shell or works as a lightweight outer layer in dry cold. It provides warmth without the heavy feel of a traditional winter jacket.

850FP goose down with a 174g fill weight offers a strong warmth-to-weight ratio, helping retain heat while keeping overall weight low. The TORAY® lightweight shell balances durability, weather resistance, and packability for repeated use in demanding mountain environments.

Its compressible construction packs down quickly and takes up less room in a climbing or trekking pack. The articulated shape also preserves reach and mobility, making transitions between hiking, climbing, and rest stops easier as effort and temperature change.

Combining 850FP warmth, lightweight TORAY® protection, and packable alpine performance, this jacket is built for fast-and-light climbing, hiking, mountaineering, and cold-weather travel where efficiency is a priority.
