Streetfighter Helmets

Does anyone know something about these helmets? I ordered such helmet from Germany and one of the problems is that I can't try it before I receive it. My old one was size M but it was too loose so I ordered a XS. Now I'm a little bit nervous - isn't it XS too small for a twenty years old girl? Too late to worry, right... Another problem is that I don't know anyone who owns a Streetfighter helmet. Is it because they are not strong and comfortable or they are just less popular here? Have you tried them?

Ive actually never heard of a street figher helmet, have you got any pictures?

XS means extra small doesnt it? Sorry im not really all that with helmets, but im sure it cant be bad. In Europe they have to be tested and DOT approved, as long as its got those, i think its an alright helmet.
