Sparco's kart collars feature state-of-the-art designs and technology. This anatomically designed 360-degree collar offers safety and comfort at a reasonable price. Extensive testing by a panel of specialists showed how effective this collar can be at supporting the neck during crash tests. Sparco's Karting Anatomic Helmet Support Collar features variable density padding to provide firmer support where the helmet is supported and softer support under the driver's chin. A unique rear "spoiler" reduces the weight of the helmet on the back.
