Stay warm and dry in cool-to-cold conditions in this lightweight, hassle-free baselayer unit. Sporting a slim fit, the one-piece suit eliminates the extra seams and potential cold spots of a traditional top and bottom layering system. Made from the warmest and most breathable baselayer in the Capilene family, this suit has a soft, stretchy feel and a smooth knit face that glides beneath layers. Featuring performance technologies that are a baselayer must, the brushed fleece interior insulates, wicks moisture and rests smoothly against your skin. Details include a high collar with anatomical shaping to hold in heat, a long center-front zipper, thumb loops to keep sleeves in place and a side-zip drop-bottom. Made of 3.8-oz. Polartec Power Dry High Efficiency fabric with Polygiene permanent odor control, the fabric is bluesign approved.
