Stylish and functional - these float vests offer a transitional floatation product allowing your child to grow confidence in the water while remaining safe. Constructed from UPF 50 neoprene, these vests are designed to fit snug and comfortable all day long with or without the use of a rashguard. Unlike our Floaties, these focus the flotation around your childs core leaving their arms free for full range of motion. Children will experience a stable float, while relying on their own body movements to move around. They are not a life jacket, nor are they rated for use on a boat. These are a float aid intending to help your children gain confidence and learn fundamentals of swimming while remaining safe in the water.
