 The Obsethed has undergone much change since the original Obsethed, the last model of the Obsethed was released for the 2011/2012 season.The Obsethed was then replaced by the SideSeth, which featured a more directional rocker profile and being in K2's Adventure category was marketed more at the backcountry skier than the Obsethed.However the SideSeth has experienced much success with inbounds skiers also.
