The Wool 2 T-Neck keeps you dry and warm whether it's worn beneath a fleece on a crisp fall evening or under a lightweight shell on the up-slog to powder heaven. Made from soft 4.4-oz merino wool with extra-fine-gauge yarn and a durable jersey construction for a luxurious hand this performance baselayer insulates even when wet naturally resists odor and stretches with your every step. Features include a high T-neck with a double-fabric layer for added insulation and to help retain its shape; raglan-sleeve seams that won't chafe beneath pack straps; and wide self-fabric cuffs that stay put. We eco-wash our merino wool for softness and to reduce shrinkage without the use of environmentally harmful chlorine. Machine-wash cold; lay flat to dry.
