Astroman Long-Sleeve Sun Shirt delivers breathable stretch and UPF 30+ protection for full-sun pursuits
What Our Gearhead® Experts Are Saying:
"This is the shirt I grab for desert hikes or any exposed alpine mission. It’s super lightweight, breathes better than expected, and the stretch makes it more comfortable under a pack. The new snap front and zip pocket give it a cleaner, more modern feel."
From high-mileage treks to sun-drenched ridgelines, the Outdoor Research Astroman Long-Sleeve Sun Shirt is our go-to for breathable protection and trail-tested performance. Engineered with bluesign®-approved recycled materials, this tech shirt delivers UPF 30+ sun protection and a lightweight feel that keeps us cool when the sun won’t let up.
The 2026 update brings a sleeker profile with a hidden snap-front closure and a secure zip chest pocket that doesn’t get in the way under a harness or pack. Movement-mirroring stretch keeps every step, scramble, or switchback feeling natural. Built for comfort, versatility, and year-round sun defense, the Astroman Long-Sleeve gets it done when it matters most.
