Use a soft tape measure or piece of twine about one inch above your eyebrows.
Make sure the tape is level all around, make it comfortably snug, not super tight.
If your measurement falls between sizes, we recommend choosing the smaller size as the snugger fit will break in after a ride or two and fit comfortably.
Measure carefully using this chart to determine your size:
Did you know that 98% of all returns are due to ordering the wrong size? Save yourself the hassle and the *return shipping charges....take the time and measure correctly BEFORE you make a purchase!ALL helmets do NOT use the same size chart. So, regardless of the helmet size you currently have or may have previously owned....it's probably going to be a different size.
