KD Sports is defying the laws of physics with their new tube the KD Gravity! With its inflatable wedged shaped stabilizer fins fitted on both the left & right sides offering riders a place to bury their legs against to keep them from flying off as the centrifugal forces increase. Rather than individual sewn-in pads to provide rider comfort and protect against abrasion, the KD Gravity features a cushiony foam-backed neoprene that covers the entire top surface of the tube, eliminating the horrible chaffing caused by inferior nylon topped tubes. The heart of all the tubes is the bladder and never wanting to skimp on quality KD Sports have equipped the new Gravity with a tough virgin PVC bladder, the same material generally reserved for 4P tubes. The Gravity is the ultimate ride for up to three full sized adults with 6x deluxe nylon-wrapped handles with neoprene knuckle guards provide a sure and comfortable grip. Dual flanking nylon web straps are fitted to the tail of the Gravity to assist with reboarding after a spill and the cover is built using a three-piece construction that ensures a gusseted side around the full permitter that creates a stronger seam and helps to reduces the likelihood of splitting edges. If you’re a thrill seeker looking for the next extreme ski tube? don’t look past the KD Gravity, with its stabilizer fins and soft top it pits rider against boat driver in a battle for the ages!
