I just got the Shark Exo Combat helmet and i have to say it's a pretty mean looking helmet. I've gone for the Exo Combat because of the integrated sun visor (it ships with one sun visor and one clear visor) and thoug it's basically a 3/4 helmet the hard mouthpiece is a nice feature, comfort wise.
It's been around +8 here in Sweden the last days and the mouthpiece helps to keep my face pretty warm. Size wise its a bit narrow in the cheek area and i've gone for a size L (I also have a Nolan helmet in M size).
Got the helmet from Chromeburner and the shipping was super fast (3 days Netherlands-Sweden).
