I use this helmet as my daily driver XC lid. Light enough and vented enough for long days in the saddle with extended coverage for confidence when riding aggressively.
I doubt I will ever use the GoPro mount, goggle guides, or flip up visor but they all seem engineered well for the guy who wants them. If I am doing any riding worth filming or needing goggles, I am always using my full face helmet anyways. The flip up visor works really well though and I wish ski helmets had this feature.
The Speed Dial fit system works perfectly one handed. I like to put it on loose so it doesn't push down my sweat band and then I dial it in tight once it's on.
Sizing guide is accurate. I measure 57 and the medium fits well.
There is enough room to slide sunglass arms under the helmet comfortably.
Buy this helmet now if you are looking for the most protection short of a full face.
