Patagonia Kids' El Capilene Bottoms:
For winter's rites of passages, like breaking tracks at first light, pre-dawn surf checks and snowball ambushes on Dad, Expedition Weight Capilene® nurtures the stoke. Its lightweight, double-faced fleece represents our warmest and most efficient moisture-wicking base layer. The elasticized waist gets kids in and out quickly and is brushed for extra comfort. A relaxed fit, open legs and spandex binding on seams lend mobility. With on-seam hip pockets.
