Arc'teryx Sima Shirt LS

The Sima Shirt LS is a lightweight, airy long-sleeve hiking shirt designed for hot, sunny trails. Durable recycled polyester fabric with mechanical stretch, a mesh back panel and articulated patterning support comfortable movement and breathability, while UPF 50+ protection helps shield covered areas from ultraviolet exposure.

A snap-front placket, pack-friendly shoulder seams and two concealed-zip chest pockets make it practical on the move. Its regular fit provides freedom of movement and comfortable layering, making it well suited to women who want lightweight, durable performance for warm-weather hiking.
