HJC RPHA-Max Helmet Sizing

Wrap a tape measure horizontally around your forehead. Select the helmet that is the closest fit to that size. A helmet should fit snug on your head. If it moves while wearing, it is too large. If it is painful to wear, it is too small.

Great Helmet

by - verified purchaser
I purchased this helmet last year for a bike trip but ordered a medium. I used it and liked all the functions in the helmet but it was tight. I think they run fairly close to others but maybe a little smaller. This spring I ordered the large and it is much better. I used the new helmet this weekend for a 3hr ride- as quiet as my solid icon, nice venting, the flip up works well and the sun visor drops low enough to cover. I still wear sun glasses as well but it's extra. My fiance received the medium and was very happy once figuring things out. A bit more expensive than others but less than many too. Overall great helmet and reasonable price.

HJC RPHA-Max modular helmet

WOW !! I have to admit this helmet was worth every penny. And Jafrum had the best price, and it only took one day to get here. The helmet has lots of features that really make it the BEST helmet I;ve ever owned. It's the quietest modular I've ever worn, and it has very good ventilation, and living in the desert, that's important. The only complaint I have is the snap for the chin strap is covered by padding making it awkward to use. I love the release for the face shield, and it's auto lock. I found it very easy to add my blue tooth to it with no need to "modify" the helmet. Bottom line, I highly recommend this helmet, you won't be disappointed, it's very well made, and it looks great too.
