The Men’s GHEE Long Sleeve ½ Zip Shirt by Mountain Hardwear is a sweat-wicking base layer that zips for venting during activity or active commutes. A sanded stretch jersey fabric stretches with your movements and feels soft next to your skin. Across the back, a jacquard panel pulls moisture away from the body and lets excess heat escape. The zip does up in a high collar. Thumbholes secure the fit.
