    Ponytail power.

    With a classic design now updated to comfortably fit a ponytail, the Black Diamond Women's Half Dome Helmet offers the protection you need on route without the discomfort and futzing you used to have to do to get your hair to stay out of your face and under your helmet. Built with a durable and shock-absorbing polycarbonate shell and EPS foam inner, the Half Dome fits securely and hassle-free on your head, adjusting via a one-handed dial system. The lightweight design also sports easy-to-use headlamp clips and a chin strap that can be quickly adjusted so you can fit a beanie under your helmet in the case of colder climbs.

    Protect your noggin!

    • Familiarity: I've used it several times

    Fits great, and dial allows comfort fitting for a range of head sizes. We all know that it takes less than a second to knock an errant rock lose and worry about hitting someone below. So protect your noggin just in case you are the person below. It's light weight and i can just clip it onto my backpack to be prepared for any situation i might find myself in!

    lightweight, sleek, and functional

    • Familiarity: I've put it through the wringer

    Of course the best part about this helmet is the ponytail compatibility, but it's also lightweight and looks good. The dial adjustment ensures a perfect fit and the ponytail friendly design really helps with those sweaty days at the crag.

    Pony Tail Bliss

    • Familiarity: I've used it several times

    I can't believe there aren't any reviews on this helmet! It's lightweight and the light blue color keeps me cool in the Moab heat. There is also an area for a ponytail/bun to fit under. This is crucial for me cause I have a thick head of hair. Great helmet all around.
