Saved my dome the first time I put it on
The first day that I was wearing the Ecrin Roc, I pulled a loose hex that would have split my forehead open, but I was saved by the ROc!@@! This helmet wears like a helmet, but protects like a hardhat. The two adjustment wheels are functional and easily operated with light gloves. I give it four stars because the rear webbing retainer creates a slight pressure point when snugged down, and I feel like the clearance between the suspension system and the shell could be reduced without sacrificing protection. All in all, a great helmet.
