For the kids that want to look just like Dad, the new Mustang MV1116 Lil Sport line offers USCG approved flotation in a kid size package. 
Mustang MV1116 youth vest 50-90 pound.
The best vest for your child is the one that fits them. A vest that is too big may come off in the water and a vest that is too small may not provide adequate flotation. THE RIGHT FIT FOR YOUR KID The easiest way to test this is to put the vest on your child, secure all zippers and buckles and tighten all belts. Once this is done, put your fingers underneath the shoulder straps and pull upwards. If the vest starts to slide over the child's face or head, it means the vest is too big and could slip off in the water. Alternatively, if you were unable to secure the zippers and buckles, it is time to move up to the next size. With the fitting process complete, you and your family can take to the water wearing the highest quality products on the market.
