Outdoor Research says:

The Astroman Sun Shirt is our best-selling lightweight, stretchy, and ultra durable fabric packed with the highest rating of UPF 50 sun protection. Named after the legendary climb in Yosemite Valley, the Astroman was built for exposed and rugged climbs, but works equally as well for hiking, paddling, backpacking, bushwhacking, or any other activity when you're headed out in the blazing sun.

Outdoor Research's 2021 Astroman L/S Sun Shirt is loose fitting, as you would expect for a trekking shirt, and yet the fabric also has stretch, this means that it moves with you even when you need to reach or twist. It makes the shirt feel really comfortable. The long sleeves add that extra coverage and protection for a range of conditions.

With the Astroman you get good wicking, breathable and fast drying fabric that works really well in warmer conditions and for outdoor activities where these are vital for staying comfortable. The vents on the back are another good feature for coping with heat, along with the UPF 50+ sun protection.
