The Arc’teryx Delta Jacket – Women’s is the brand’s most technical fleece midlayer, designed to deliver high-performance warmth that goes well beyond casual comfort. Built with innovative hollow-core fibre fleece, it provides an exceptional warmth-to-weight ratio while remaining breathable, soft, and durable for active use. The smooth-faced exterior resists abrasion and layers easily under a shell, while Phasic™ AR II panels under the arms add stretch and actively wick moisture during high-output movement. Articulated patterning and an updated, roomier fit enhance freedom of movement and all-day comfort across a wide range of activities. A full front zip allows for easy temperature regulation, and flatlock seams improve next-to-skin feel. Versatile enough to wear as a standalone jacket or a technical midlayer, the Delta is a refined essential for mountain systems and everyday performance.
Air permeable fleece mid layer. Thermally efficient, comfortable next to skin.
Arcteryx’s Phasic™ AR II engineered polyester fabric is soft, offers stretch and thermal comfort, and is made with fibers that help wick moisture.
