Bern summer helmet?

[PKalow]

So, I tried searching for this and couldn't find a thread, I'm sure there's one somewhere, but I couldn't find it.
Anyway, I was wondering if anyone knew the difference between the summer/winter helmets made by Bern, specifically the Baker? Other than the obvious hat liner. Thanks alot
