The Men’s Nano-Air Light Insulated Jacket is designed for dynamic mountain activities that alternate between intense movement and short periods of rest. Its highly breathable construction and stretchy insulation provide lasting comfort without the need to frequently change layers as activity levels vary.

The shell and lining are made from 100% recycled polyester with a stretchy ripstop construction. These materials offer abrasion resistance, allow unrestricted movement and feel comfortable against 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 movement. An articulated fit and strategically placed low-profile quilting enhance mobility during climbing and mountain trekking.

The centre-front zipper features a chin garage for added comfort. Two zippered handwarmer pockets and a zippered chest pocket provide convenient storage without adding unnecessary bulk when wearing a backpack or climbing harness. The jacket can be packed into its chest pocket for compact storage and easy transport.

The low-profile cuffs are snag-resistant, stretchy and can be pulled up over the forearms to improve ventilation and regulate body temperature. A cleanly finished hem helps retain warmth. Its lightweight construction makes the jacket an excellent insulating layer for high-output activities in cool conditions or as a midlayer beneath an outer shell.
