Layered Warmth for Mission-Ready Mobility

The Arc'teryx LEAF Atom LT Hoody Gen 2.1 is a versatile insulated mid-layer that’s ready to handle standalone tasks or pair seamlessly under a wet weather protective shell. Engineered for special reconnaissance ops, it combines lightweight warmth with a minimal profile for unrestricted movement and maximum adaptability.

From the CLIMASHIELD 2oz Combat Fibrefill insulation to the rugged yet breathable mini-ripstop fabrics, every detail is battle-ready. An insulated hood provides optional coverage when needed, while cable management loops and zippered pockets keep your mission essentials dialed in.
