Summary: Like the Edelrid Ultralight, the Petzl Ecrin has been a staple in the suspended-shell helmet market for many years, and for good reason — it’s very durable, well ventilated, and easy to adjust. It is showing its age, however, lacking in padding, especially on the chin strap, and the vents aren’t shrouded or protected. Those with narrow heads may experience side-to-side fit issues, and ponytail wearers may experience a little discomfort from the rear straps’ plastic connection tab. The Ecrin is very headlamp compatible, which is not surprising, considering that Petzl is also one of the world’s leading manufacturers of headlamps.
Pros: Easy to adjust; accommodates headlamps well.
Cons: Needs more padding.

There is a reason the Ecrin Roc is the most rented helmet in the world: it is nearly indestructible (more than we can say for our noggins), extremely adjustable and unquestionably comfortable. Yeah, there are less expensive, lighter-weight options out there, but the Petzl classic has been relied upon countless times and for numerous years by guides, clients, kids, etc. Its dial adjustment system works for all type of head shapes: mongoloid, egghead, pinhead, and so on. Combine it with a bicycle-style helmet, and your quiver is good to go for all adventures.
