Query: Great looking and functional

I originally ordered the large size vest but it was too small and I had to return it. I needed the vest sooner than later and the vendor allowed me to order the X-Large and get a refund on the original Large purchase when I shipped it back. They were very easy to work with.The vest itself is well-constructed and worked great. We went to Maui and I used it probably 6 times snorkeling off the beach. As other reviewers have mentioned it does have a tendency to ride up a bit since there is nothing at the bottom to hold it in place. But overall it didn't ride up any more than any other snorkel vest I've ever used. The valve which allows you to adjust the air level was awesome.It look great as well! I would definitely recommend this to anyone who needs a snorkel vest!
