Get the most distance on your swing with the SkyTee! Using brush bristles instead of a hard tee reduces friction between the ball and the tee, ensuring further drives. The brush also provides a consistent height on every swing. We have put our tee through the ringer - several professional golfers have tested the SkyTee and have found it adds 4-7 yards to drives on average. And don't worry, our tees meet all USGA specifications.
