Chocorua Midweight Men's 100% Merino Wool Crew
There's a reason the Chocorua is our best-selling men's top. This 100% merino wool crew delivers the perfect balance of warmth and breathability for three-season adventures—warm enough for winter layering, light enough to wear solo when the sun breaks through. The 235 g/m² midweight fabric regulates temperature whether you're breaking a sweat on the trail or sitting still in a tree stand, and the natural odor resistance means you can wear it day after day without that synthetic funk. Named after Mt. Chocorua, the iconic bare-summit peak in New Hampshire's White Mountains, this crew is built for men who measure their days in miles and elevation gain.
