berns are cpsc according to the sticker inside and en1078.
the reason i went skater style was for the reasons you mentioned. it just feels safer and sturdier, tho that is just my opinion. i have read all there is about cycle helmets that i can find on the net.
i am of the same opinion, based on research papers, that a smoother rounder helmet is less likely to cause rotational injury, to snag and come off, less chance of road debris getting thru as well. i also agree that the straps should terminate inside the helmet.
i hate helmets, i really do. but i'm a father and a husband so responsibly i have chosen to wear one all the time now.
at least this one is stylish and seems comfy enough. i like the idea of the winter kits as well.
