Arc'teryx Sima Shirt SS

The Sima Shirt SS is a lightweight women’s hiking shirt made from durable recycled polyester with mechanical stretch. Its airy construction, mesh back panel and articulated patterning help keep movement unrestricted on warm-weather trails, while the UPF 50+ rating provides sun protection on covered areas.

Designed for hot, active days, the shirt combines practical trail details with pack-friendly comfort. Shoulder seams are positioned for freedom of movement beneath pack straps, and concealed-zipper chest pockets keep essentials accessible without removing a pack. It suits hikers seeking breathable, durable coverage for sunny conditions.
