The Funky Trunks Neon Razor Boys Trunks are different than anything your youngster has ever worn before. They’re comprised of a special blend of C-Infinity fabrics, presenting high-definition colors in neon-razor designs that have the staying power to withstand years of wear and wash. Chlorine resistance is also a constant, as kids can go through hours of swimming training without the usual sag, fade, and loss of shape that happens with other inferior swim-trunks.
