The HALTI Optifit is the optimum fitting headcollar. Designed to allow a customised fit, the fully adjustable noseband sits comfortably on all dogs including short nose tyes. The side straps are designed to follow the natural contours of a dogs face preventing interference with his mouth. The HALTI Optifit combines the key features from the original HALTI with the added benefit of more adjustability. The simple design works by steering the head and therefore controlling the direction of the dogs movement, enabling the handler to take and keep control. Large.
