Measure your head as shown!

1. Use a metric cloth tape measure for best results.
2. Place tape measure like a headband, one inch above the eyebrows and above the ears (not on the ears). Match measurement to chart bellow.
If your measurement is between sizes, we suggest that you order the next size larger to avoid a size exchange or return.
Individual head shape vary, so some people never find an exact fit. Here is the standard for most of the helmets we carry.*

Hat size, if you know what that is:
Xtra Small 6-1/4 to 6-5/8
Small 6-3/4 to 6-7/8
Medium 7 to 7-1/8
Large 7-1/4 to 7-3/8
Xtra Large 7-1/2 to 7-5/8
Xtra Xtra Large 8 to 8-1/8

Or centimeter around your head:
Xtra Small 52cm to 53cm
Small 54cm to 55cm
Medium 56cm to 57cm
Large 58cm to 59cm
Xtra Large 60cm to 61cm
Xtra Xtra Large 62cm to 63cm

* ANY helmets returned due to ordering the wrong size, buyer will be responsible for any and all return shipping charges coming and going for the proper size exchange. No exceptions.
