Capilene® 4 Expedition Weight has the highest thermal performance in the Capilene family. Soft, stretchy and compressible, it's warmer than our old Capilene 4 baselayer, breathes better and dries faster. A smooth jersey face glides beneath layers and the brushed fleece interior retains warmth, wicks perspiration, and feels soft against the skin. With a full coverage collar, full-length front zip, offset shoulder seams and shoulder yoke, and zippered handwarmer pockets. Made with 5.9-oz Polartec® Power Dry® with Gladiodor® odor control for the garment. Recyclable through the Common Threads Recycling Program.
