I'm not gonna lie, I bought this helmet because I think it looks bitchin'. I love the way the vents look, like the air intakes on a turbocharged engine. Turns out it was a good purchase. It vents really well, even at low speeds. It's comfortable (I've worn it for 100 mile mtb races with no problems). It protects better than road helmets, without sharp points to catch on things and with better coverage on the back of the head. The vents even work particularly well with the helmet mount for my NiteRider lights. It's not the lightest, but I think it's better. I'll buy another when I destroy this one.
