We call these skis BREAKTHRU, because you'll learn how to deep water start and the basics of water skiing quickly and easily. They feature an oversized profile, parabolic side cut, tapered tail and comfortable adjustable bindings. The stabilizer bar keeps the 47" long skis steady while the student is learning to ski. Fiberglass reinforced nylon rudders increase stability and tracking. Designed for skiers under 100 lbs. The adjustable bindings fit child size 12 to adult size 5.
