Men's Astroman S/S Sun Shirt

The Astroman Sun Shirt is our best-selling lightweight, stretchy, and durable fabric packed with UPF sun protection. Named after the legendary route in Yosemite Valley, the Astroman was built for exposed and rugged climbs, but works equally as well for hiking, paddling, backpacking, or any other activity when you're headed out in the blazing sun.

Made with a bluesign® approved recycled nylon blend, this breathable, quick-drying fabric moves with you thanks to movement-mirroring stretch. The updated design features a hidden snap front for a clean, functional look, a left zip chest pocket for secure storage, and a raised heat transfer logo for subtle detail. With a UPF 30 rating and standard fit, it offers reliable coverage and all-day comfort from trail to crag.
