The littlest ones in the family can enjoy the water too in a Stearns-  Infant Nylon Vest. It's specially-fitted for children 20 to 30 lbs., with an extra contoured float above the neck—like a pillow—to encourage face-up flotation. A rescue handle allows adults to easily move the child from the water or the boat. One adjustable chest strap and a leg strap ensure a tight fit at the pool, beach or lake. Durable nylon construction and Crosstech-  flotation foam, along with 1-in. webbed straps, will allow you to use the Transport Canada approved vest season after season.
