The moisture-wicking Kids' Capilene Midweight Zip-Neck is made of 100% recycled polyester fabric that has hollow-core yarns and a diamond-grid back to trap warmth and speed-up dry time. We've added HeiQ Fresh durable odor control to keep things fresh. Zip-neck pullover styling with stand-up, doubled-fabric collar; internal neck tape for comfort and a locker loop for hang-drying. Deep, center-front zipper vents body heat and has a kissing-welt zipper garage for low-bulk comfort next-to-skin. Raglan sleeves provide mobility and comfort under pack straps; thumb holes at sleeve openings for secure hand coverage. Forward-set, flatlock seams lend a great fit and minimize chafing. Low-bulk construction allows for easy layering under midlayers and outerwear. Drop-tail hem provides additional coverage in rear. Hand-me-down ID label. Fair Trade Certified sewn.
