I have several helmets but my favorite is my newest one a Joe Rocket Carbon Fiber this thing is amazing with it's fit and finish but the best part is it weights about half as much as the rest of them. I'll post the pics when I get a chance.
This is the one I use now. I've got 5 total but no pictures right now. I practice my airbrushing on a couple of the older ones so they don't stay the same color or design for very long. The others are past their prime so they've turned into decoration hanging on the wall. Sorry for the shitty pic.
Here is the newest Scorpion helmet I added to the collection, I bought this one for my wife because she wasn't very keen on the green Scorpion Warhawk. This one is the Scorpion EXO-400 Paradise in Sky Blue.
