"What Our Gearhead® Experts Are Saying: ""I wear this shirt for everything from guiding long routes to summer road trips. It’s light, stretchy, and doesn’t cling when I sweat. The UPF protection is legit, and I can roll up the sleeves or button it down depending on the conditions—super versatile and feels great all day.""When the day calls for exposed approaches, high-elevation climbs, or long hours under the sun, we count on the Outdoor Research Astroman Long-Sleeve Sun Shirt to keep us cool and covered. Designed with climbers and guides in mind, this shirt delivers performance where we need it most—breathability, stretch, and full UPF 30+ protection. The lightweight stretch fabric moves with us on steep approaches and through scrambles, while the button-up style offers airflow and versatility from trail to town. Roll-up sleeve tabs and a zippered chest pocket add practical functionality, making this a go-to for any sun-soaked mission."
