hi guys im gonna buy an airoh trr helmet ! how acurate is there sizing guide as no trials dealers near me ???

 

It worked for me. I put a tape measure around my head, and according to the size chart that makes me a Medium. So that's what I bought and it seems fine. I still can't get over how light the helmet is, having been used to wearing a full-face that must have been at least double the Airoh. Whether that amounts to anything at all in real terms, I wouldn't like to guess.

Also got a medium and fits true to size. Very comfy helmet and don't even know its on after a full day.

The sizing is pretty bang on. Ordered a Medium and fit very tight at first but after a few outings the lining ''packed in '' and now fits perfect. I can see the plastic add on vent covers possibly getting knocked off along the trail..Amazing helmet, money well spent!!

Love my TTR. 

I have a very oval head so found it a tiny bit snug front to rear when getting the correct size by measurement, but is hardly noticeable as long as I don't sinccthe chin strap to tight.  

Thanks for your input guys, helmet ordered yesterday and arrived today, sizing is spot on ! and the helmet just feels quality
