Designed to mimic a bouncing action, the Zoggs Back Float will help your little one learn to swim confidently, calming and independently. The adjustable fit ensures that your child is securely strapped to the float, giving sufficient body support and allowing his or her arms and legs to move freely. The swimming aid is equipped with removable layers which can be removed to adjust the support your child receives from the float. The float fits children between the ages of 2 and 6 and is made from heavy duty EVA foam. Children should always be supervised by a parent or guardian. This is not meant to be a life-saving device.
