This helmet is very comfortable on my head, and gets lots of air flow. And the full face part makes me feel a lot more confident on the downhill.
I havent had the helmet for very long, but I detach and attach the chin guard regularly. So my only concern is how long the clamps will last as they seem to snap in and out pretty hard. But it does feel like its built tough, so I highly recommend it.
I've been eyeing this helmet for a while, I do a lot of climbing but really enjoy technical rocky DH on the return. The removable chin bar is a great concept and pretty well executed here, it is clunky and not very efficient to remove or re-install (the 3 levers are hard to open close - it just doesn't have a nice method). That is really the only negative, other than the MSRP.
I was worried that it would be hot - I had the original Bell Super and it was poorly ventilated. This helmet is leagues better and surprisingly the best-ventilated helmet I've had.
The fit is good, adjustments for fit are easy to access. The rotational MIPS is a great advancement in this technology as well.
