Swimming aid: The Bestway FISHER PRICE SWIM PAL is a great tool for introducing your little ones to the water. The vest is lightweight, you don't have to inflate it so it is ready to use for swimming lessons and increasing water safety. The strap between the legs prevents the vest from slipping off the child's body and is adjustable, making it easy to adapt to the height of the child. Use only under the surveillance of an adult even in the shallow water.
