Review on O'Neill Men's Superlite USCG Life Vest, Medium, Pacific/Smoke/Black/White by Chp Rodgers

Let me start by saying we are short people. 5ft 6in and 140lbs is our tallest family member. We first ordered 2 of these little ones, when they arrived only teenagers could click them comfortably. Then I ordered two medium ones and they are too big for adults. Due to the lack of life jackets in stores and online I don't know what to do about it. Wear a small one that looks like a very tight corset, or a medium one that would take a lot of work when swimming. Regardless of size, adults or teenagers, when we sit in them (kayaks, jet skis) they lift up and create a gap between our shoulder and the shoulder of the jacket to put our arm through. If there were other options, I would not recommend this one.
