The Optimos Articulated Pivotal Dart is designed to follow the horses movements. The dart is placed above and behind the shoulder to allow the horse to move in an exuberant manner similar to that of an articulating truck. The front of the blanket will move, turn and extend to follow natural movement while the blanket stays in position without pulling forward or slipping. This allows the shoulder to be free while maintaining maximum coverage at all times.
