Paddle Pals is the patented swim jacket with attached arm bands for teaching kids to swim. The safety shoulder harness prevents the vest from sliding off, and the child from removing vest without help. Fits child 30-50 lbs (14-23 kg) with an adjustable chest strap and a quick-release rear safety buckle for a great fit. The durable polyester material and multi-panel design provides superior comfort, and doesn't chafe like nylon. This is not a life saving device a competent adult swimmer should be in the pool supervising the child during use.
