Climbing is undeniably cool, and at Black Diamond we believe that our helmets should not only protect your head, but look good, too. We design our helmets to deliver the highest standard of protection while staying lightweight, streamlined, and damn good-looking. From the ultra-light Vapor worn by the world’s best climbers to our classic Half-Dome worn by climbers for over twenty years, Black Diamond helmets make safety look good.
Reviewers praise the Half Dome as a comfortable, lightweight helmet with an easy rear adjustment dial, headlamp clips and room for a beanie. Climbers, canyoneers, cavers, mountaineers and youth programs use it, and several say it protected them in falls or rockfall. Critiques are limited: about a dozen found it sits high, feels shallow or runs small for larger heads, a few say ventilation is limited in heat or prefer the previous version, and single reviewers reported adjustment straps popping out, the cradle dislodging and dial wheels breaking.

"Pretty comfortable, but not perfect. For the price, that is to be expected. It appears to be very durable. The straps are pretty comfortable and you tend to forget they're there. The headlamp attachment system is kind of annoying. Solid helmet for the price. Better than getting domed by a rock without one."
"This helmet is a great option for casual climbers. The comfort and price point make this a no-brainer. My son and I each have a half-dome and we've got an extra for when friends join us. The one hand adjustment works well and the helmet has enough vents to remain comfortable when its hot. The attachment points do a good job holding a headlamp in position. I've was also able to use my old Petzl headlamp with a separate 4 AA battery pack in the back without having it feel off balance or too heavy."
"Have taken this helmet both climbing and hiking some bigger rock scrambles. Overall the fit/adjustment is good. It can be hard sometimes to get a snug fit that doesn't start hurting your head but overall once you find that fit there is not a lot of movement. The helmet is not super heavy either which is good for longer efforts. The headlamp clasps are also super handy and secure the headlamp great."
"The adaptability is perfect. The color is so cool."
"The BD Half Dome helmet is my personal favorite helmet. It feels very comfortable and secure while climbing. It's very lightweight, easy to adjust, and stays in place very well for me and my buds who have it. The design itself manages to feel very durable without being bulky, and the ventilation is a nice touch to it. It's all around a very nice helmet and I am very happy with it. If you are a climber looking for a helmet, this is the one to choose."
"Fits comfortably and the adjustment system is easy to use, even with gloves. The weight isn't terrible for the price"
"The helmet is light and breathable and it fits comfortably and snugly once you adjust the neck strap correctly. There’s a little strap in the back poking out that would interfere with a headlamp with a rear battery sitting correctly. Over great helmet though."
"Recently purchased this helmet before going out to Moab for some sport climbing, and thoroughly enjoyed it. It’s very lightweight and I was easily able to size the helmet to my head with the rear adjustable notch and the chin strap. Easy to haul around and fit in my pack nicely. It sat fine on my head and I could even fit my hat underneath it. I would recommend this helmet to anyone who is new or experienced!"
"I bought an orange Half Dome helmet today at the Salt Lake City store. It fits like a dream, love it!"
"Nice fit, love the dial in feature in the back!"
