I have a Giro helmet, i cant remember the model name because its a few years old and its my brothers old helmet. Its perfect, fits well, comfotable, looks good and its lasted for about 5 years through me and my brother but unfortunatly they stopped making them. I ordered a hex because my brother wanted his helmet back as he's started riding again. Anyway thats not the point, the point is i got it, it was uncomfortable, it sat on the top of my head, the adjustment thigns in the top of the helmet that determines the height of the helmet didnt lock in place, you'd move it to one position and as soon as you put the helmet on, it would move down on or two positions. Thats probably me being picky but i can imagine it being tidious after a while. The only good thing is the looks really. I persauded my brother to have the new one and i keep his old one though so, problem solved.
