TYR Hydrofoil Pull Float Pull Buoy

1st, you must wear a brief (grape smugglers) when using a pull buoy of any type. Jammers will let all buoys easily slide out. 2nd, pull buoys should easily fit inside of your quads (inner thigh.) If it doesn't, exchange it. Last, this is the best pull buoy for me. I have bigger quads, so it sits tight through 10 X 500's without slipping. When I purchased this buoy, I thought about using some surf wax on it because it was much different then my foamier-double-barrel Styrofoam-versions.) The surf wax helps, but it isn't necessary unless you have jammers on. This buoy floats more then anything I've ever used (I weigh 185lbs.) and it's great for open-water swimmers who regularly train in the pool.
