Climbing Helmets. A must for any climber, because rocks are harder than heads. Light, expanded foam helmets are good for when you fall off. Shell-and-cradle helmets are good for when stuff is falling on you. We stock a range of helmets from leading brands Petzl, Black Diamond, Grivel, and Edelrid. Don't leave it to chance, protect your most prized possession with one of our selected range of climbing helmets at BananaFingers.
