"It's very well made and looks very durable. Like that it has the "heads up" feature. Kind of doubt that it would fit a child smaller than 20 lbs, but maybe."

"We used this vest for my 12 month old son. We took him swimming in the pool for the first time while on vacation. It was a well constructed vest and easy to use."
