Arcteryx says about the Adahy Hoody Men's
On its own or as part of layering system, the Adahy Hoody provides insulation for spring and summer backpacking and trekking. The lightweight, soft Torrent™ fleece’s stretch improves ergonomic freedom and helps hold the trim fit close to the body for maximum fabric efficiency and layering comfort. A snug fitting hood adds warmth. Minimalist by design, it is light, easily packed, and integrates with other Arc’teryx Traverse products to create an efficient clothing system for backcountry travel.
