A heavyweight performance mid layer ideal for winter training and cold-weather adventures, the Elemental Long Sleeve Zip combines go-anywhere style with the technical performance of merino RealFleece™. This stretchy top also features zippered hand pockets for securing small essentials and flatlock stitching and offset seams for chafe-free comfort. Superfine merino fibers are brushed to create icebreaker RealFleece™, a natural fleece that warms and breathes next to your skin. Inspired by nature, icebreaker harnesses the performance qualities of natural fibers to offer an alternative to clothing based on petrochemical synthetics.
