Arc'teryx Delta

The Arc'teryx Delta is a technical fleece midlayer built for efficient warmth without unnecessary weight. Its hollow-core fibre construction delivers an excellent warmth-to-weight ratio, while the smooth face improves durability and makes layering comfortable.

Breathable, soft and durable, it combines wicking Phasic AR II underarm panels with stretch and articulated patterning for unrestricted movement. It suits high-output alpine activity, climbing and everyday camp use, and works equally well beneath a shell or as a standalone warming layer.
