Lopt is a lightweight down vest that combines warmth, durability and low weight, making it ideal for alpine activities. The outer fabric is made from a castor-oil-based ripstop material that provides high tear resistance without adding extra weight. With an 800-fill-power white goose down, the vest delivers effective thermal insulation while keeping weight low and pack volume minimal.

The design includes two front pockets with zip closures, one of which can be used as a stuff sack for easy transport. The close-fitting hood is designed to sit comfortably under a helmet, while an angled two-way front zip offers ventilation options and is fitted with a chin guard baffle for added comfort.

Double fabric over the shoulders and a seamless construction in the most exposed areas reduce wear and chafing. Reflective details at the front and back increase visibility in poor light conditions.
