I recently crashed wearing a a very expensive top of the line bicycle helmet(gira atmos if any of you are cyclists) and was pretty seriously injured. I dont remember the crash but a whitness said i took a turn at walkin speed and the front slid out and i smacked my head on the ground, here are some pics of the damage. Warning: Fairly Graphic.

This injury happened despite he wearing the right gear and going very slow. I have a concussion and a gnarly scar for life as even the local plastic surgeon couldnt sew it up. So i need something with facial protection. As i am a road cyclist, a mountain bike helmet is too bulky and un aero, thats the reason im looking at these helmets.
