The Rev series is an entirely new collection from Head. It is intended to be a technical, all-mountain line of skis. Like all of the Rev skis, the Rev 90 implements a combination of rocker and camber for all-conditions performance and a progressive sidecut that eases turn initiation and improves edge contact while in the turn. Head calls the new technology Era 3.0. The Rev 90 is on the wider spectrum of the Rev series so it will perform in softer snow conditions. It is intended for more advanced skiers.
