The Delta jacket for women stands out for its ability to provide effective insulation while remaining surprisingly lightweight. Its hollow-fiber fleece generates consistent warmth without adding bulk, allowing you to cope with the temperature variations encountered when climbing or progressing over rocky terrain. Phasic™ AR II inserts under the arms promote greater stretch and active moisture management, providing noticeable ease during sustained climbs. Its redesigned cut, slightly looser than previous versions in the body and sleeves, enhances comfort and freedom of movement.

A durable construction that is comfortable to wear every day

The fabric features an extremely durable smooth surface, designed to withstand abrasion from a backpack or repeated friction during rocky approaches. Flatlock seams minimize chafing and make layering more comfortable under a waterproof jacket. The full-length zipper, combined with a soft chin guard, allows for quick donning and extra protection when the wind picks up. Zippered handwarmer pockets and a laminated chest pocket secure essential items while maintaining the clean profile characteristic of ARC'TERYX.

A versatile, warm, and breathable midlayer

Weighing only 195 g, the Delta can be worn as a warm layer on its own at camp or under a technical jacket during activity. Its breathable technical polyester, developed using Japanese expertise, promotes optimal heat regulation on days of intense activity. Its slim fit hugs the body without restricting movement, making it easy to layer over a lightweight base layer. This versatility makes it an essential piece for alpine environments, rock climbing, or fast-paced outings where you need a balance of protection, mobility, and lightness.

Add the Delta to your gear and enjoy a technical fleece that is as lightweight as it is high-performance for your summer adventures.
