Stio was tied with Patagonia for most comfortable sun shirt in this test, thanks to the extralight and extremely stretchy Helion material. It also crushed moisture management and was only a few grams of water shy of being bone-dry at the end of the test.
This high-performance quarter zip is from Stio, a company based in Jackson Hole, WY, where snow flurries aren’t unheard of in the summer, so you can bet they know how to stay warm and dry. The Basis Power Wool Zip Neck is a great layering piece that’s breathable and comfortable. Ultra-fine merino wool delivers that silky-soft feel against your skin, while a polyester weave on the outside provides some added durability. The fabric features something called a “high-efficiency grid backer,” which traps warm air and allows for moisture transfer for faster dry time. What’s more, thumbholes help your sleeves stay in place whether you’re running or cross-country skiing.
