try em on first! Klim Xl fits my head nice, 509 XL carbon ripped my ears off trying to get it on.Undecided
I just ordered the new Klim. check out canada motorcycle, they are on sale there (386.00).
As far as goggles go, again try them with the helmet and choose the one that seems to fit best on your face with the helmet.
Yes, that is the theory, but it's bollucks (no offence). Unless the goggles have some sort of funky frame design, pretty much all goggles will work with most helmets these days, and I find it more important that the goggle fit your face well (as that is where you end up with fogging issues, not wear it meets the helmet). That is why I said find the helmet that fits your head best, then try different goggles with that helmet to find the one that best fits your face. The foam on goggles now is generous enough to conform to the lines of the helmet (so you don't get that gap), but I find the way it fits around your temples, cheeks and nose to be the most important, as if that doesn't have a good seal, that is where the majority of fogging issues will come from. Moisture will make it's way into the goggle through those gaps, and lead to fogging.Generally the theory is that you should get the helmet and the goggles from the same manufacturer as they are designed to work together properly (shape wise). I use a top of the line Fox helmet because it is very light and has great ventilation but some brands of ski/sled googles don't seem to fit right at my temples.

The HJC RPHA-X look like they will be a decent helmet.
