Kant-See-Bak blinds (sometimes referred to as "Dolly Varden" blinds), are perhaps the most widely used type of blinker in harness racing. They are designed to prevent horses from seeing behind, so that they are more inclined to focus on going forward.

This model is designed for use with an Extended Head Bridle - available in Black, Blue, Yellow, Green, Red and White. It comes with a black noseband fitted, but the blinds can be customised through the separate purchase of coloured nosebands - available in Blue, Brown, Yellow, Green, Red and White.
