The Arc'teryx LEAF Delta AR 1/2 Zip Hoody was born in the mountains and adapted for the field. Originally inspired by alpine climbers, this midweight performance fleece now pulls double duty as a cold-weather base or standalone tactical layer built for operators, adventurers, and anyone who moves with purpose in demanding conditions.
Crafted from Polartec® Power Dry® High Warmth fleece, the Delta AR features a voided grid interior for high thermal efficiency and breathability, paired with a smooth outer face for easy layering under plate carriers or outer shells. The integrated balaclava-style hood provides convertible face and neck protection, while thumbhole cuffs and articulated patterning keep movement unrestricted and layering seamless.
Whether you're rucking into altitude, grinding through cold-weather ops, or posted up at a windy hide site, the Delta AR Hoody keeps you warm without weighing you down.
