The North Face Men's GTD Performance Crew is a short-sleeve knit crew that wicks away moisture and sweat from skin, while mesh underarm panels enhance breathability to keep you cool and comfortable for backcountry hiking, on downhill singletrack mountain bike riding, or on long cross-country runs. Wrapped seams work to eliminate abrasion and a UPF 30 will keep your skin from being burned during a day of activities.
