Some of the fondest childhood memories, and adult memories for that matter, are made white-knuckling outside of the wake on an inner tube with your good friends. The Liquid Force Zip! 2 Person Tube is a surefire way to bring your friendship to the next level because this durably constructed towable tube is a g-force fiend. Luckily for you (and your friend) its padded handles have neoprene knuckle guards so an epic tubing session doesn't leave you looking like you just played bloody knuckles...
