Arc'teryx LEAF Delta AR 1/2 Zip Hoody – Polartec® Power Meets Tactical Precision

Mountain-Built. Mission-Ready. Exceptionally Versatile. 

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.

Why We Love It

It’s the kind of technical midlayer you forget you’re wearing—until it saves your ass in freezing wind. The Delta AR delivers next-level warmth-to-weight ratio, stealth-fit ergonomics, and breathable performance that moves with you, not against you.

Ideal For:

• Cold weather tactical operations

• Midweight layering under plate carriers or field shells

• Mountain trekking, climbing, or rucking

• Extended field deployments

• Anyone needing versatile insulation without bulk
