“The most comfortable tech shirt I’ve worn—on par with a five-year-old cotton hoodie,” one tester says. The smooth, silky feel comes from the sanded stretch jersey polyester fabric, which has a brushed inner surface for an ultraplush touch. Very stretchy fabric (15 percent elastane) accommodates all motion.
Excellent (as we expect from a synthetic). “I never felt clammy,” says one Colorado tester who wore it biking, backcountry skiing, and cross-country skiing. Even in the toughest conditions—long, strenuous days in cold rain—it kept a Washington biologist feeling dry while he was tracking wolverines in the Cascades.
A chemical antimicrobial finish creates a physical barrier against bacteria, making it better than average for a synthetic: One tester didn’t even need to wash it after a three-day backcountry hut trip in Colorado’s Never Summer Mountains.
