Stay cool and protected under any sun with the Astroman LS Sun Shirt's stretch and ventilation

What Our Gearhead® Experts Are Saying:


"I love the Astroman LS Sun Shirt for everything from desert hikes to alpine approaches. It's lightweight, super breathable, and offers enough stretch that I never feel restricted when scrambling or casting a fishing line. Plus, the built-in UPF protection gives me one less thing to worry about on long days outside."


Whether we're hiking exposed ridgelines or paddling along sunny coastlines, the Astroman LS Sun Shirt from Outdoor Research keeps us shielded and comfortable. Built with lightweight, stretchy fabric and boasting UPF 30+ sun protection, this shirt lets us move freely and confidently without overheating under the sun's full force.


The technical blend of nylon, spandex, and polyester delivers both abrasion resistance and breathable comfort, while strategically placed snaps and underarm gussets enhance mobility and venting. Hidden features like the zippered chest pocket and snap-up collar offer extra versatility, making it a staple whether we're climbing, trekking, or traveling.
