Amazing helmet for climbing! Has already saved the noggin quite a few times!
I purchased this helmet for outdoor climbing. My favorite parts about this helmet when originally purchasing were: - The cheap price point compared to other helmets of the same quality - The stylish design when compared to other helmets in the same price range - The very light weight profile - The ability to hold your helmet light up - The ability to save my head from disaster After having purchased and used the helmet a few times, I would say that one of my favorite things about it is definitely the light profile. I have found that I forget that I'm even wearing the helmet sometimes! It is very comfortable and the ability for it to fit most sizes of heads is also pretty wonderful. Be cautious when looking into sizing. My girlfriend was purchasing the purple version of this helmet and believed she would be a small. When actually trying on the small at a local REI, we were really glad we checked it out first. The small is definitely for the head of a child! Medium is likely applicable for most people who don't have a very small or very large head! I honestly have no cons that I can come up with for this helmet as of yet. For the quality and price, and a name brand like Black Diamond, you really can't go wrong with this! Get out there and climb some rocks!

my helmet isn’t just part of my gear — it’s my lifeline
10/10 – Tough, Lightweight, and Cave-Proof I’m a spelunking guide and use this helmet for hours every week underground. It’s lightweight, comfortable, and fits securely even during climbs and tight crawls. After months of scraping against sharp rock, it’s still in great shape. If it can survive caving, it can handle anything.

Great helmet, horrible Amazon delivery.
This helmet is comfortable, lightweight, visually appealing, and at a great price. I can’t comment of the durability just yet, but thanks to the delivery from Amazon, it’s already aged like a fine wine. My package arrived late, in a taped up and misshaped resemblance of a cardboard box, and appears to have been delivered by Ace Ventura himself after being kicked down the street and closed in the door once or seventeen times. Every other helmet I’ve owned wants you to replace it after a big impact of some kind. By the looks of box this thing came in and how the packaging inside that box looks, it should probably head straight back for the warehouse it came from for warranty replacement. Unfortunately, I need to use this tomorrow (thankfully it arrived late but ‘on time’ still) and don’t have the time to return it and get a replacement that isn’t scraped and scarred like I’ve been climbing with Alex Honnold for the last few years. This is not an issue with Black Diamond and the quality of their product, this thing is bomber and looks really sweet. Amazon in the other hand, if you need tonight see more than a roll of packing tape to fix a box that has been destroyed and it’s contents falling out, cut your losses and send a new item to your customer. I would have been embarrassed to deliver this package if I was the driver. Maybe that’s why he delivered it to the wrong house, thankfully I have good neighbors and this thing is ready to protect my head from whatever is falling from above.

Great Helmet!
Purchased for protection during underground mine exploration. Once received I fitted it to my head and installed a Fenix HM61R with strap. I'm very impressed with the fit and finish on this helmet. I opted for the blue model, and the color is exactly as pictured. Helmet is very well made, comfortable, and I really like that it features tabs to hold the headlamp strap in place. I wore this one for about 6 hours underground last weekend and had no issues with discomfort or bad fitment. Saved my noggin on a couple of low hanging walls. Please note: I HIGHLY recommend opting for the Med/Large size if you're an adult. I originally tried the Small/Med size because my measurement was in that range and the helmet sat way too high on my head. I exchanged for the Med/Large model and the fit and adjustability was perfect. Definitely recommend this helmet at this price.

Check the size before ordering
The helmet it's good. Lightweight and comfortable. But... I returned it because the size S/M was too small. It seems more like it would fit a child. A shame because I like the adjustment system and it feels comfortable. More than the Petzel Boreo I bought. And looks nicer. I didn't try the M/L size, I think it's too big for me. After reading the specifications and reviews, I decided to order the Boreo.

Quality Climbing Helmet
Purchased with Rock Empire starter kit, great quality helmet and fits him a treat. the adjustable head band ensures good fit and fit snugly where it should do. These are not a life time purchase but at this price can afford to be exchanged if damaged at any stage.

Perfetto!
niente da dire sul prodotto,ottimo, giunto nei tempi indicati con imballaggio ben confenzionato. Il casco Half Dome è adatto all'arrampicata in falesia proprio per l'ampia visuale che offre ,non chiude sulla fronte permettendo di vedere senza piegare troppo la testa.
