Purchased from MEC for $55 plus tax about two years ago, daughter has outgrown it. Barely used. Recommended weight range is 4 to 9kg (8-20 lbs). Designed to keep a little one supported with their head above water. The collar supports your baby's head, while adjustable shoulder buckles and a leg buckle secure the PFD in place. An adjustable waist strap and webbing harness add security and comfort. https://www.mec.ca/en/product/5047-042/Puffer-PFD
