Conquer each lap in comfort with this Nike boys’ jammer that lets you perform at your best. The swim jammer is made from soft tricot fabric, with added stretch for freedom of motion and a front lining for modesty. An interior drawcord helps to keep it in place as you dive into the pool. Designed with a snug fit to prevent drag in the water, the jammers have flat seams that help to minimize chafing. A large Swoosh at the side and smaller one at the back add pops of color to the sleek, athletic design of the jammer swimwear.
