The Men’s Nano-Air Light Vest is designed for dynamic mountain activities that alternate between intense movement and short periods of rest. Its lightweight construction and high breathability provide comfort across varying levels of physical exertion without the need to frequently change layers.

The shell and lining are made from 100% recycled polyester with a stretchy ripstop construction. These materials provide abrasion resistance, freedom of movement and comfort next to the skin. A durable water-repellent finish made without intentionally added PFAS helps protect against light moisture.

The 40 g/m² FullRange® insulation combines warmth, stretch and exceptional air permeability. It retains warmth during periods of rest while allowing excess body heat to escape quickly during strenuous activity. Strategically placed low-profile quilting enhances mobility and makes layering easier.

The centre-front zipper features a chin garage for added comfort. Two zippered handwarmer pockets provide convenient storage and warmth, while the zippered chest pocket securely holds small essentials. The vest packs into its chest pocket for compact storage, making it easy to carry in a backpack.

The armholes and hem feature a clean, low-bulk construction that minimises excess material and makes the vest comfortable beneath an outer layer or when worn with a backpack or climbing harness. Its lightweight design and functional insulation make it a practical choice for mountain sports, travel and everyday activities in cool conditions.
