To determine your helmet size, you will need to measure your head as follows. Take a soft measuring tape and wrap it around your head about 1 inch above your eyebrows and ears. Most helmets are measured in centimeters, so unless you love calculations, measure your head in centimeters. For example, if you measure the circumference of your head, and it is 56cm, you will wear a 55-57 cm helmet. Also, all Slokker helmets come equipped with a sizing dial located at the rear of the helmet. With the turn of a dial, you get even, fine tuning adjust-ability to make sure that your helmet fits as snuggly and comfortably as possible.
Don’t have a soft tape measure? Take a piece of string and wrap it around your head, and then measure the string.
