ExOfficio Sol Cool Long Sleeve Half Zip

The hotter the sun gets, the more you need to cover up to stay cool. “That’s why I love this top,” says one Grand Canyon ranger. “I can roll the sleeves down and flip up the super-tall, 4-inch collar, and I’m still comfortable on 80°F days.” Credit the mesh side panels and unique, 50+ UPF face fabric: The poly/rayon blend is embedded with xylitol, a tree-based sugar that cools the shirt—and your skin—when it comes into contact with moisture. Our testers affirmed the tech, saying they noticed a definite cooling-down effect when they started sweating in the Sol Cool. The fit is loose and breezy. $75; 8 oz.; men’s S-3XL; exofficio.com
