Top rated features at a can't-beat price. That's why we call our Xero Pro wetsuits flexible performers. Designed with our exclusive Xero Foam, his unique material out performs all other neoprenes on any level. Its oxygenated process creates a neoprene sponge that's softer, more flexible and warmer than its competitors. Featured throughout our entire Xero wetsuit line, you can expect your next session to be one of your very best. The 403 Xero Pro chest zip full suit for boys offers superior warmth and is ideal for water temps ranging from 52 degrees to 65 degrees. Imported.
