i heard once that if you have a ten dollar head, you should buy a ten dollar helmet. also, you spend 1/3rd of your life on a matress; so buy a good mattress also.
There's a bunch of Bern helmets, the most expensive one is $65
All I have to say is head injuries are the most fucked up thing ever. Make sure you get a helmet that will actually protect your brain. If you have ever been in the presence of a really bad head injury. You wouldn't give a fuck what was steezy or not. You need something that will protect your domepiece.
