I'll just add that Conner didn't swim in his. He wore it while we were under way. When we were at anchor, he didn't wear it as he wasn't left on his own at any time.

If the goal is to have them wear it while at anchor and swim with it, then that may be harder to find something that is really comfortable and also offers the same level of safety. Our goal was simply - a vest that could keep him afloat safely if he fell off the boat, but more important a vest with harness so he never fell off the boat.
