FEND Helmet Fit Guide
1. Find a Measuring Tool: Use a string, shoelace, or USB cable to wrap around your head just above the eyebrows.
2. Mark & Measure: Mark where string overlaps and measure against a ruler or yardstick.
3. Choose Your Size:
FEND One Helmet -
• Small: 21½-22in (54-56cm)
• Medium/Large: 22-24in (56-61cm)
FEND Super Helmet -

• Medium: 22⅜-23¼in (57-59cm)
• Large: 23¼-24⅜in (59-62cm)
If you’re in-between sizes, we recommend sizing up.
