Changing my helmet was way overdue. I transition from my Petzel vertex vent with face shield and ear muffs. The Protos is a little more comfortable and secure then my Petzel helmet. I feel like I have a smaller head size, which would always need to secure my old helmet chin strap. With the Protos the back tension clip holds the helmet tight to my head without the need to secure the chin strap. I love how the Protos ear muffs tuck beneath the helmet, which is a real bonus, no more getting caught in branches which traversing a tree. The face shield on the protos is a little bulky, compared to the petzel visor, so I am still getting use to that. I plan to get the Protos integrated safety glasses in the future. Overall awesome helmet, that I would recommend if you have the money.
