The Vortex Combos are O'Brien's go-to wide-body skis, designed with extra surface area to deliver maximum support and lift especially for larger skiers. This added surface makes deep-water starts a breeze and allows for smooth, powerful carving turns. Plus, the wider design lets you ski at slower, more relaxed boat speeds while using less horsepower and fuel to get up and going.
