The Ecrin Roc is no longer available. The next closest option, and a good one at that, is the Petzl Elios. Check out our complete Climbing Helmet Review to compare current helmets.
This is an adjustable and ultra-durable climbing helmet that has been around for ages. It is not as light as newer models, but is still a great pick for rescue, caving and heavyduty climbing situations such as you find on big walls. Talk to any climber that has been on the scene for at least five years and chances are they have an Ecrin Roc in their closet somewhere. Additionally, due to the onesizefitsall design, this is a great helmet for groups or institutions.
Many colleges pick this bulldog of a helmet for group outings that range from cragging to ice. The Ecrin Roc fits most heads, is fast to resize and takes a beating extremely well. That said, most climbers will prefer a more comfortable, adjustable and cheaper helmet like the Petzl Elios. If you want the ultimate light weight helmet, check out the Petzl Meteor which won our Editors' Choice award.
