I've used some different helmets including a specialized, an older Remedy, Bell Drop, 661 Comp II and Fox Rampage. Out of all of them the Bell and the Giro definitely fit the best, however when it comes to ventilation the Giro out performed all of them. I also prefer a buckle strap instead of a D-ring strap. The Remedy has a lower profile chin guard that allows you to have a much better field of vision, where the 661 comes up very high into your line of sight straight in front of you.
Bottom Line: Great fit, great ventilation, not too heavy, and much better field of vision. I highly recommend this helmet.
