I have used helmets from Kask, Edelrid & 3 versions of Petzel.
In my opinion none of these fitted as well as the Protos.
I often didn't get a good seal on the earmuffs also due to having a narrow head.
The recessed earmuffs of the Protos does not restrict them from sealing well. They can be dialed into the pressure you require to get a comfortable fit. I feel this adds more protection than a higher rated muff that is not correctly sealed.
The cons for me are, I didn't like the colour options. Too bright.
The visor is not recessed into the the helmets profile when up, causing it to catch on branches of tight trees. It's also a bit clunky & does not offer me enough dust protection. I am looking forward to a new option for this.
