The moisture-wicking Kids' Capilene Midweight Bottoms are made of 100% recycled polyester fabric that has hollow-core yarns and a diamond-grid back to trap warm air and dry quickly. We've added HeiQ Fresh durable odor control to minimize stinkiness. The baselayer pants feature easy pull-on styling and a self-fabric waistband for next-to-skin softness. Gusseted crotch provides comfort and unimpeded mobility. The pants layer easily under midlayers and outerwear, with forward-set, flatlock seams that minimize chafing; offset cuff seams and low-profile stitching minimize bulk under boots. Hand-me-down ID label. Fair Trade Certified sewn.
