Arc'teryx LEAF Cold WX Bottom AR | Midweight Merino Wool Base Layer for Cold Weather Operations

Regulate your core temperature and stay mission-ready in the cold.

The Arc'teryx LEAF Cold WX Bottom AR is a midweight, high-performance base layer engineered for cold-weather operations. Built from ABMT 180gsm Nylon Core Spun Merino Wool, it delivers the natural warmth, breathability, and odor resistance of Merino with the added durability of a nylon core. Designed for professional use, this bottom excels in variable cold climates where moisture management and insulation are critical.

The Cold WX Bottom AR wicks moisture away from the skin to enhance thermal efficiency while maintaining comfort during extended wear. A gusseted crotch design provides unrestricted mobility for active operations, while the lightweight construction retains warmth even when wet. Ideal for use under combat uniforms or outer shells, this layer performs as hard as you do when temperatures drop.

 

Why We Love It

Because it’s what a true cold-weather base layer should be- quiet, durable, and built to perform under pressure. The combination of Merino wool and nylon core-spun fibers creates the perfect balance of comfort, warmth, and strength for the field or the range.
