Leatt Convertible Helmet Sizing - Advice

Hello All, wondered if anyone knows whether a Leatt convertible lid (Enduro 3.0) sizing comes up smaller, larger, or 'just right'.

I have a 58cm head, but I wear a 59cm motorbike skid-lid, and the Leatt M is 55-59cm, and the L is 59-63cm. ย This means I should get a M, but if they come up small I might need a L.

I know I should find somewhere and try one on, but there are no nearby stockists that I can find, so purchasing online it is.

Hopefully someone has one and can advise.

R

I have a 2.0 and my friend has a 4.0. When I tried hers, the M fit me and I'm a 58mm as well. M in Oakley, L in Giro. Assuming the 3.0 is the same size (I think the different versions seem to be on the outer shell not the inside), I'd say M is the right choice.

I really like mine, use it as a half shell for all my winter riding. It's a bit warm in the summer but probably the comfiest/best fit helmet I've had for ages. Not yet tried the full face.ย

I wear a medium 58 arai and had a large enduro 3. It will adjust down to way to small for my head. The chin bar comes with another set of pads to adjust the fit as well. I used the standard as they were fine.

Smashed it up in the end but it properly did its job. Great lidย

Hi

I have a 58cm nogging and use the Enduro 3.0 in the medium 55-59cm size, I've swapped in the smallest of the 2 sets of pads (included) and the fit is comfy.

Nice helmet. Although I don't use the half shell mode and instead leave it in 3/4 size. It's a bit warm for summer like this but I got it in August so it got chilly fairly quickly after then.
