Astroman Sun Shirt by Outdoor Research

Inspired by one of the hardest long free climbs in Yosemite Valley, El Cap veteran Hans Florine collaborated with a design team to create the perfect woven technical shirt. Built with UPF 50+ sun protection, this shirt will protect you from the harsh rays while on the rock wall. Enhanced with a snap under the chin—our Sun Snap Collar™ provides added sun protection for your neck.
