HELMYY frequently asked questions
Questions
Answers, before you ride.
How do I choose my size?
Find your HELMYY size by wrapping a soft tape measure around your head, ~2-3cm above eyebrows and ears. If you're in between sizes, we recommend sizing down to ensure a snug fit.
| HELMYY SIZE | HEAD CIRCUMFERENCE |
|---|---|
| S | 53–56 cm |
| M | 57–58 cm |
| L | 59–60 cm |
| XL | 61–62 cm |
| XXL | 63–64 cm |
