In extreme cold, selecting the right layering system leaves no room for error. That’s why we created our dense, wind-resistant Expedition Weight Crew and Zip Mock T Neck Tops—the final insulating layer in our integrated system. In the frigid outdoors, millions of tiny wool fibers hold in your body heat. Its flat-stitched seams eliminate chafing when you’re on the move. Made with our itch-free, naturally odor-free Merino wool, it’s an essential piece of cold weather outdoor gear. Both tops can be worn as a casual sweatshirt. Cold water machine washable. Hang dry.
