Does anyone know how the Smith I/O's will fit with my Giro MX10 helmet?

I've got the I/0 and the Giro G10 MX set up also. It works nicely. I wish the goggle strap was longer to fit around this helmet. My strap is maxed out on a medium helmet. Maybe some rubber on the inside of the strap would give these a chance of sticking on top of the helmet when they are not on my face. When not in use these goggles just slide of the back of and dangle. Not the coolest look but I really don't care while I'm walking to the lift. It's just kind of a pain if I have to take the goggles off on the mountain. Still this is caused more because I the design/visor on the helmet than the goggles.

Yeah man for sure. There is quite a big lip from the lens to the front edge of the goggle, but I'll post another more side-view pic for you.

Thanks for the pic man. that does help a lot.

Dude they fit so nice. The tops of the I/O are nice and flat to fit perfect with it. You probably will need to extend the strap out most of the way, but it fits. Worst part is the clip at the back of the goggles, which interferes with the goggle attachment a bit on the G10.
