Very good tip . . . thank you.
I was going to buy the floor model but for some reason it looked used to me. I examined it all over. It was kind of dirty on the top and the pads looked a little used. I asked the salesman when helmets were returned if they were put back on the floor. He said if they looked new and unused they were. (REI has a one year return policy) I then asked him how would you know if someone fell in the helmet but it didn't show a crack? Then I asked him to get me a brand new one from stock. He did and everyone is happy, well at least I am knowing I didn't buy a used helmet.
