A refreshingly wet joy ride for two (or three). The Wave Whirl is a hit with many camps across the country and will sure to be a hit with yours! These water tubes are made to handle the use and abuse that water tubing is all about. The Wave Whirl is manufactured of the same durable vinyl materials as The-Blob® and assembled with the quality and workmanship you have grown to trust over the years. The inner-tube is replaceable with a standard tractor tire inner-tube.
