The Arc’teryx Delta 1/2 Zip Top – Men’s is a highly technical fleece midlayer engineered for comfort and performance across a wide range of activities and output levels. Built with innovative hollow-core fibre fleece, it delivers exceptional warmth for its weight while remaining breathable, soft, and durable. The smooth-faced exterior resists abrasion and layers cleanly under a shell, while Phasic™ AR II panels under the arms add stretch and actively wick moisture during high-output movement. Articulated patterning and a roomier, updated fit provide ergonomic freedom and improved comfort, whether you’re skinning uphill, climbing, or moving fast in cool conditions. A deep front zipper allows for rapid ventilation, and flatlock seams enhance next-to-skin comfort. Equally effective as a standalone or layering piece, the Delta is a versatile essential for technical mountain systems.
