Riddle me this: You have a single layer that wicks sweat, dries quickly, weighs next to nothing, inhibits odors, and is built with sustainable materials? Don't let the features list fool you - the new Enigma Collection does all that and more. Blended drirelease merino wool and E.C.O. (Environmentally Correct Origins) fabrics provide temperature-regulating warmth that's committed to your comfort and to the conservation of the outdoor places in which we love to play. A flat seam construction ensures that fabrics won't bunch, rub, and chafe uncomfortably, and thumb loops keep your sleeves where you want them. Layer under your favorite hard shell jacket or wear on its own as a lightweight next-to-skin top.
