    Don't break your noggin!

    • Familiarity: I gave it as a gift but have feedback to share

    I bought this as a precaution as my brother is a disaster and is starting to climb. Although he may not need it he got this to not break his head open, the large fit his big head, and the color fit his big ego, so maybe he will use it... Probably not, he has a hard head, but it is there if he needs it to save the head of the punk:)

    But really a great helmet.

    Great helmet, can't beat the price

    • Familiarity: I've put it through the wringer

    I've had this helmet for a couple years. I like that it's lightweight, comfortable and very adjustable. Whether I have my hair in a braid or low ponytail, it can adjust to fit. The price is great too! I got it for my husband I liked it so much.

    Great helmet, can't beat the price

    Great Light Helmet

      Despite how light this helmet is it also seems very safe to me. this is great quality helmet for a great price!!! great balance between quality and price!! would highly recommend for beginner climbing and everyone else looking for a solid helmet!

      Great Fit

      • Familiarity: I've used it several times

      I have used this helmet for about 3 weeks now and I love it. With the adjustable sizing you can get a really customized fit. This helmet is also super light so you don't even realize you are wearing it. Check this one out if you are looking for a new climbing helmet at a great price.

      Comfort is Key!

      • Familiarity: I've used it once or twice and have initial impressions

      Love this helmet. Perfect fit and good breathability for those hot afternoon beat downs from the sun! The adjustment makes ease of loosening or tightening depending on what you are doing and preference of fit in the moment!

      Great First Helmet

      • Familiarity: I've used it once or twice and have initial impressions

      Just picked this up as my first climbing helmet. Saw a lot of them out there at Smith Rock! Overall, it is comfortable, light weight, and easily adjustable. The dial in the back allows for quick and simple adjustment of the size.

      I got this on the recommendation of a seasoned climber and I have no complaints. It's a classic from Black Diamond and is nice and affordable. Definitely stoked with this purchase!

      Does the Trick

      • Familiarity: I've put it through the wringer

      The Black Diamond Half Dome is a really great basic helmet. It has an easy to use wheel adjuster similar to a Boa to adjust the tightness depending on if you wear a beanie or hat under it. I've used it for about a year now for sport and trad climbing and it performed as much as any helmet is expected to. It's served as solid protection for climbs with surprise roofs that I've definitely knocked my noggin' on a few times and has saved me some brain cells.

      I only had a few issues with it, and this could be my own individual problem/my head not being right for this helmet. I noticed after wearing it for extended periods of time such as on multi pitch climbs or long belays, I start to get tension headaches from the pressure that is applied by the bands on the inside of the helmet. I tried to mitigate this by loosening the fit, but I found that this only makes the helmet move around too much and didn't make my headaches go away. I also attribute the headaches to possible allergies, so take all of that with a grain of salt -- my partner uses the same one and has never had an issue with headaches!

      I also wish the helmet covered the front and back of my head a little more, and though this could be a size thing I'm worried that if I went up another size the helmet would just be too big. Otherwise this helmet does the job and won't break the bank!

      This is a photo of me wearing it trad climbing in Big Cottonwood Canyon, Utah last summer.

      A Classic First Helmet

      • Familiarity: I've put it through the wringer

      I got this helmet when I first started climbing and canyoneering in Utah. For almost a year, it has got the job done protecting my noggin, from canyons to crags. It feels super solid and can be adjusted a good amount, making it a great helmet for lower price ranges. The only reason I marked it down a little is because of the ventilation, which isn't quite enough for the hotter days in the desert.

      Versatile Helmet - Tried and True

      • Familiarity: I gave it as a gift but have feedback to share

      I gave this as a Christmas gift to my friend who wanted a helmet that could do multiple activities, but mostly for use climbing and canyoneering. Having a hard shell style helmet like this is pretty important for the abuse helmets take when canyoneering, but this is lighter than some of the clunky, bulkier canyoneering helmets I've seen so it is better for climbing at the crags. She definitely loves it (especially since BD released some more girly colors) and says it's the best helmet she's owned and she would definitely recommend to everyone! This is BD's classic helmet that has been put to the test by adventurer's everywhere and you can't ask for a more simple, sturdy helmet.

      Comfortable and lightweight

      • Familiarity: I've used it several times

      Its comfortable because it is light weight so you won't feel the headstrap dig in much at all. Fits well over winter beanies and low profile enough that hoods fit over it without too much pull. I would recommend to anyone that doesn't have a huge head. If you do have a huge head, try it on in a store first before ordering. In fact I would recommend that no matter what.

      Good First Helmet

      • Familiarity: I've put it through the wringer

      This made for an excellent first beater helmet. Its lite and adjust well. I found it did fit small on my head for the M/L I ordered. Maybe my dome is just bigger than I thought. Great price for quality though. I definitely recommend this for a first helmet.

      Great for the price!

      • Familiarity: I've put it through the wringer

      This is a great buy for the price! It's easily adjustable and comfortable as far as helmets go. I have it in small medium and it fits great. Another bonus to this helmet is all the cool colors!

      Daily Rider

      • Familiarity: I've put it through the wringer

      Durable, Reliable, Lightweight. These helmets are a great bang for the buck. If you have put off buying a helmet pick one of these guys up and let your Mom relax!

      Great All Around

      • Familiarity: I've used it several times

      I think this is a good helmet for the price. I sized up so I can wear it in winter with a hat under it so it is a bit loose on me during the summer even after tightening the back. But I expected that to happen. The only downside I've experienced is that it doesn't vent that well and my head gets super sweaty.

      Nothin' Can Knock My Noggin

      • Familiarity: I've put it through the wringer

      I picked up this bad boy in a sleek Ultra Blue, and he hasnt let me down since. Personally, I haven't had anything larger than a pebble glancing off my dome at my local crag, but this helmet feels very very study! I would recommend it to any climber looking for a solid helmet.

      first helmet

        was long lived and never had any problems, but gifted it to my brother after having it the first year still protecting his head when he is out and about on the rock.

        Is there a reason I couldn't use this helmet on kayaking adventures? What is the difference, if any, between a kayak helmet and a general purpose climbing helmet?

        It can’t be recommended. Helmets for different sports are designed for the impact risks of those sports. Climbing helmets are designed to protect your head from falling rocks or gear and from you hitting your head on the rock face, from little bump to whipper: usually a single major impact. Kayaking helmets are designed to protect your head from smashing it on rocks while rolled upside down or swimming (and also from your boat), but you’re more likely to hit your head multiple times: multiple big impacts. That’s one reason why climbing helmets are often lower profile, more like bicycle helmets, than kayaking helmets; they’re designed to take one major impact, then the styrofoam inside gets deformed and they’re likely toast (also, kayaking often has a colder environment, water). Also, kayaking helmets are designed to take abuse from any angle, climbing helmets less so, they’re really designed for those rocks or that gear falling and landing square on your noggin. If you’re still tempted, call or email Black Diamond and ask for a tech specialist’s input.

        I didn't see any indication if this helmet...

        I didn't see any indication if this helmet is certified as CE EN 12492 or UIAA 106?

        I'm in between sizes in nearly everything....

        I'm in between sizes in nearly everything. Any recommendations for someone with a 21 7/8 head?...I would like to use it both for summer and winter (with and without a beanie underneath).

        I would suggest a medium large also, and with the scroll wheel in the back it will help dial in the fit. If you still wanted to try the helmet on, most local outdoors stores should carry this helmet. I know my local REI carries this helmet.
