This brightly colored nylon Swim Tube Trainer encases a strong rubber Air Core tube that fits comfortably around the child. Buoyancy, comfort and fit can be adjusted by the amount of inflation. The Air Core tube positioned around the child's upper body allows freedom of movement and permits the child to float in an upright position or in a swimming position on front or back. The tank top design with bottom strap instills confidence in both child and parent as it is difficult to be removed without a supervisor's help. For ages 2 to 6 years.
