Layer your girl up starting with the Patagonia Girls' Micro D Bottom and keep her warm and cozy as she learns the joys of sledding and making snowmen. This bottom is made with partially recycled polyester fleece that provides warmth and dries quickly. The fold-over elasticized waist, flat seam construction, and soft cuffs prevent chafing, and the bottoms work well under snow pants for outside fun and on their own around the house or at the lodge.
