Finding a Helmet for a Big Head
If your head measures over 60cm, many helmets will feel tight or sit too high, which reduces protection and comfort. A helmet in the right size sits low and level on your head, with the padding in contact all the way around.
Everyday Helmets in 2XL
The Azur L61 is a lightweight leisure helmet with a rear dial fit system, available in 2XL for bigger heads. It suits commuting, bike paths and weekend cycling.
Full Face MTB Helmets in XL and XXL
The Leatt MTB Gravity range comes in XL (61-62cm) and XXL (63-64cm) in selected models and colours, giving bigger-headed mountain bikers full face protection for downhill and the bike park.
How to Measure Your Head
Wrap a soft tape measure around your head about 2cm above your eyebrows and ears, at the widest point. Measure two or three times and use the largest number. If you measure 61cm or more, look for XL or XXL helmets.
Getting the Right Fit
A helmet should sit level on your head, about two finger widths above your eyebrows. The side straps should form a V just below each ear, and the chin strap should be snug enough that only one finger fits underneath. Tighten the rear fit system until the helmet does not rock when you shake your head.
If a helmet only fits with the fit system fully loosened and still feels tight, go up a size.
Big Head Helmet FAQs
What size helmet do I need for a big head?
If your head measures 61cm or more, you will usually need an XL or XXL helmet. Check the size range on each product page.
Why does my helmet sit on top of my head?
The helmet is likely too small. A helmet that sits high leaves your forehead exposed and will not protect you properly.
Are XL and XXL helmets as safe as smaller sizes?
Yes. Every helmet we sell meets Australia's mandatory safety standard, whatever the size.
What is the biggest helmet size you stock?
Our largest helmets are XXL, fitting heads up to 64cm, in selected Leatt MTB Gravity full face helmets.
