The O'Brien Junior Vortex Combo Water skis were designed for learning deep water starts as its wider in the tips and shorter in the length. The Jr. Vortex are very stable and make learning a snap. A smaller version of the adult Vortex combos has all the features in a smaller size. The Jr. Vortex includes a stabilizer bar which helps the just learning little guy stay upright and stable and keeps them under control. Once they have mastered getting out of the water and staying upright, simply remove the bar and the wide design will still keep them stable. The Jr. Vortex comes with the 600 Junior adjustable bindings which will fit a kids size 2 all the way up to an adult 7.
