The Astroman Long Sleeve Sun Shirt is built for climbing, hiking, and year-round adventures that demand lightweight sun protection and unrestricted mobility.

Made with a bluesign® approved recycled nylon blend, it delivers breathable, quick-drying performance with movement-mirroring stretch for all-day comfort. Updated for Spring ’26, the design features a hidden snap front for a clean, streamlined look and a left zip chest pocket for secure storage. The UPF 30 fabric guards against harmful UV rays, and the standard fit layers easily for versatility across changing conditions.
