Brand: Dynafit
Model: Trail Tee
“It’s the next best thing to naked,” swears our tester, who wore this gauzy tee on muggy, 85°F hikes along Michigan’s Indian River. Credit the hollow-core polyester fibers (which channel heat away from the skin) and smooth mesh panels on the back and underarms, which vent high-sweat zones. And at 3 ounces, this shirt weighs less than some sunglasses—but costs more than your cable bill. dynafit.com/en
