Hey Luke, Don't know if you're new but let me help you out a bit. Have you tried search? Just based on a few of the recent lifejacket threads on here in the last two days I can tell you that the Gooru is extremly thin and does not float you well although it does float you a little better than the A-10.
Also, why not ask about the Gooru in the heading rather than making people click to read. You'll have more people who have the vest click on your thread that way.
