This thread needs to be deleted right now before it goes any further lol. Andrew, just do a search for comp or uscg vests. I GUARANTEE you will find a number of posts with over 100 posts in each one. I never tell people to search because I feel like that takes away the point of a message board, but in this instance, you will understand when you do so. In fact, I hate when people say "use the SEARCH before posting" because the point of a message board is to answer each persons questions individually and although it maybe very similar to prior posts, it is still different. If everyone just used the "search" then there would not be a message board.
Ok rant over and now my answer: I HATE USCG VESTS BUT WAS FORCED TO BUY ONE because you have to have it for McCormicks and the closest one I could find to a comp vest was the Hyperlite Murray vest. It is the least bulky of the ones I have tried and I too ride an A-10 exclusively when I use my comp vest, so I think you will feel pretty similar to me when it comes to the Murray vest. It still feels like a USCG vest, but it is the least pregnant feeling out of all of the USCG vests that I have tried.
