Product Description Zoggs Zoggy Backfloat is designed to create buoyancy whilst your child is actively trying to swim. The adjustable strap goes across the chest for a secure fit. The Backfloat is ideal for giving children more independence in the water but children should still be closely supervised for safety. Other key benefits are that it supports with body position as well as independent arm and leg movement. There are removable layers in the float allowing you to remove one layer at a time which will reduce buoyancy as your child gains confidence in the water.
