Astroman Long Sleeve Sun Shirt – Women's

For trail runners and hikers logging long hours in exposed Southern sun, the Astroman Long Sleeve is our go-to UPF sun shirt for staying covered without cooking. Stretchy, moisture-wicking fabric moves with you and dries fast, so you're not dealing with that clammy, stuck-to-skin feeling mid-effort. It packs down small enough to justify bringing on any outing.

• UPF-rated fabric blocks harmful UV rays on exposed ridgelines, open trails, and long mountain days — smarter and more consistent than reapplying sunscreen
• Lightweight stretch construction wicks sweat fast and breathes well enough to handle Southern heat and humidity without trapping warmth
• Long sleeves protect your arms without restricting movement — cut to work with your stride, not against it
• Low-profile fit layers cleanly under a pack without bunching or riding up on extended efforts
• Packs down small for easy stashing — earns a spot in your kit even when you're trying to go light
