Our junior size rash guards are a must for your junior guard program, a day at the beach or the pool. Made with UV 50 Sun protective quick-drying stretch lycra. Kids love the feel of this super soft fabric! We have added two extra side panels on the waist to make them a little more snug fitting and prevent the rash guard from riding up while surfing or running around. We also added a "boardie-strap" to the hem. This little elastic loop allows you to tie your rashguard to your boardshorts to keep it from creeping up your stomach.
