I love the way that my KASK fits, but people are right about it falling apart. My face shield screw mounts broke off and even the threaded insert popped out. I’m changing my face shield to a wire-mesh Husky one, since I have Husky earmuffs anyways.
I saw the new Petzl Alveo with ANSI approved face shield down at the TCIA Expo, and all that I can say is WOW! That is a nice looking, well-made helmet, as is all of Petzl’s gear. Didn’t get to try it on, but if it fits as well as my KASK, then it’ll be the next helmet that I purchase.
The newly redesigned Petzl Vertex and Vertex Vent, also come equipped with mountable face shield adapter holes.
