The Bell K.1 Pro Auto Racing Helmet is great for open wheel racers, closed car racers and kart racers who demand superior features including light weight, excellent fit and multiple ventilation options.
Proper helmet fit is vital to the performance of a helmet during an impact. For the helmet to perform properly during an impact, it must stay securely on the head. Measuring the head is only a starting point for the entire sizing procedure. Due to varying shapes, heads that are apparently the same size when measured by a tape may not necessarily fit the same size helmet.
A small metal tape measure or a cloth tape may be used to make your initial measurement. You can also use a string, which can then be laid against a measuring tape.
Measure the circumference of the head at a point approximately one inch above the eyebrows in front, and at a point in the back of the head that results in the largest possible measurement. Take several measurements. The largest measurement is the one you want to use.
THE HELMET SHOULD FIT AS SNUGLY AS POSSIBLE – IT WILL BREAK IN AS YOU WEAR IT.
