The best way to get the right fit in your special needs helmets is to measure the circumference of your head. This is most easily done with two people because it is very difficult to hold the string or cloth tape measure in the correct location. This is especially true of the back of the head, where you cannot see the measure as it wraps around your skull.
Specific instructions to measure for your Special Needs Helmets
The best way to measure for your special needs helmets is to use a cloth tape measure or a string. You want to measure about one inch above the eyebrows and above the ears. It is important to keep the string level so that your helmet will rest comfortable on your head and not obstruct your vision. Then just find out the number of inches and refer to our sizing chart to get the helmet that fits your skull.
