Fantastic, but with some size issues
Nice light helmet that's comfy enough to wear all day.
As others have noted, us big headed freaks may have some trouble...I have a large, and with a beanie on I can barely squeeze into it with it fully expanded. If my head were a millimeter bigger, I'd have some problems with this helmet.
If you're also sporting a big melon, I'd recommend scoping the size chart and consider a different helmet if it doesn't look promising...otherwise, this helmet is simply fantastic.
