With our new Men's Smartloft 60 Hybrid Half Zip, you get the sweat management, temperature regulation, and odor control benefits that synthetic and down jackets cannot provide. That means you're insulated for high-energy, cold-weather activities and don’t' have to shed. Featuring a DWR weather protection coating and stretchy, soft-brushed Merino wool next to skin, this warm midlayer will help keep you comfortable for a day's worth of skiing, hiking, running, and more.
