Chamonix 3

Fits very well. Feels light but secure.

The roller wheel at the back is poorly designed and very annoying, it is much too big and very loose so it continually loosens through rubbing a against the collar of my shirt or cycling jacket as I cycle. The y-joints on the straps are large and uncomfortable, and it is not possible to adjust the length of the upper parts of the straps, only move the plastic y-splitter back and forward along them (with difficulty).

The trifix adjustment system is not only extremly difficult to adjust (feed strap through), it is also impossible to adjust the helmet correctly using it. If the front straps are too long and you feed it through the trifix system to shorten them, the rear straps become too long and there is no way of taking the excess slack out of the system (tightening the chin strap doesn't do that). The trifix buckles are also huge and sit very uncomfortably on the cheekbones, which is a shame since the rest of the helmet is very comfortable.

Helmet is comfortable on my head only issues is the Y strap cannot be adjustable it can irritate your ears
