Men's Merino Wool Long Sleeve Henley — MidweightSame performance as our crew neck, with a three button placket that gives you a bit more venting when you need it. Made from 100% merino wool at 190 GSM, the henley is a midweight layer that handles everything from a brisk morning hike to a full day on the slopes. It also looks good enough to wear on its own at camp, around town, or after a day outside. Merino wool keeps you warm when conditions drop and helps cool you down when you're working hard.
