Petzl Meteor

About the helmet itself, it is very good. It’s so lightweight you barely notice it, it has copious ventilation, holds a headlamp, and is easy to adjust. The only detail I don’t like is the magnetic buckle. It’s fiddliness was tough to cope with when I was wearing gloves, and was almost as tricky barehanded. Impatient, I sometimes let the chin strap all the way out and pulled it off  overhead like a T-shirt. A minor glitch in an otherwise excellent and versatile helmet.
