"The North Face Elevation Long-Sleeve Shirt pairs FlashDry XD fabric with UPF-rated sun protection, so it wicks sweat and blocks sun through long days on trail instead of doing just one job well. A standard fit keeps full range of motion through the chest and shoulders, whether it's working alone on a warm hike or layered under something heavier when temperatures drop. What Our Gearhead® Experts Are Saying:""I wore this on a long, exposed ridge hike in full sun and never felt that sticky, soaked-through feeling I get from a basic cotton tee. The fabric kept pulling sweat away the whole climb, so I stayed cool instead of overheating under the sun."""
