Black Diamond Vapor Helmet

In use, what can you say? Most of the time you don’t know it’s there; it's incredibly comfortable due to its light weight and the ventilation works well; certainly much better than the first generation lightweight helmets like the original Petzl Meteor. In fact, a friend recently suggested you could quite happily wear it on the walk-in using it as an alternative to having to take a sun hat, it's that unobtrusive.
