The NRS Youth KidSkin Pants are the perfect layer for keeping your kids warm on the river or at the waterpark. NRS's Kid Skin Pant Features: Neoprene provides superior insulation for activities in the water. 0.5 mm neoprene is stretchy, so it won't restrict movement and is super comfortable. Titanium laminate adhesive reflects body heat back to the body for maximum warmth with less bulk. Flat lock stitching gives you strong, durable seams that hold up to kid's boisterous activity. High cut waistline and drawstring with barrel lock provide good back coverage while seated.
