Tested for two years in top west coast pools, the Aquajogger Jr. flotation belt provides buoyancy and total freedom of movement so children can effectively focus on the many skills involved in swimming. The Jr. belt comes in blue or green, with a free, 24-page illustrated game book featuring 30 all-time favorite water games and swim skill building activities. The Aquajogger Jr. belt is a learn-to-swim tool, not a life preserver, and should only be used under direct supervision of an adult or aquatics professional. Unlike many flotation products for children, the Aquajogger's patented design properly positions flotation for accurate swimming and maximum freedom. The soft, flexible foam is contoured to a child's small waist and the adjustable design accommodates most 3 to 12-year-old children comfortably and securely.
