I just bought the RED HiFi and it fits great. But the helmet I initially wanted, the RED Theory, I found on sale for around the same price as what I paid for the HiFi. Do all RED helmets fit the same? I have only been able to find the Theory online so I couldn't try it on in person.
ehh, they really do not fit exactly the same, is it going to be a huge difference, or a difference that the extra padding will work it, prob not. i would say that you can safely go for the helmet and be 99% fine.
