Description

How does the Half Dome balance durability with weight? Featuring a rugged polycarbonate shell and an EPS foam liner, this hybrid construction provides high-impact protection against overhead hazards while maintaining a lower profile and a lighter weight for all-day comfort. Can I adjust the fit of the helmet while wearing gloves? Yes. The updated suspension system includes a low-profile tension dial designed for one-handed operation. This allows for quick, precise micro-adjustments on the fly, even when wearing technical gloves or dealing with changing layers. Are the headlamp clips secure enough for technical rappels? Absolutely. The helmet is equipped with streamlined, integrated headlamp clips that provide the most secure attachment points on the market. Does this helmet provide protection against side or rear impacts? The Half Dome's co-molded EPS foam and polycarbonate shell provide reliable coverage around the sides and back, meeting international safety standards for climbing and mountaineering. Is the chin strap adjustable? Yes. The Half Dome features an updated, low-profile chin strap with adjustable dividers. This allows you to customize the fit for maximum security and efficiency, whether you're climbing in a t-shirt or geared up for cold-weather alpine missions.

    • Very good buy!
Size: Medium/Large Color: Slate
Great helmet for the price. Very comfortable and lightweight. I wore this on a canyoneering trip with a hat underneath it. Worked very well. Caught two blows to the head which the helmet deflected nicely. Only marked the helmet a little. Very good quality. Highly recommend to family and friends.

    • Solid choice
Size: Medium/Large Color: Denim
I've used a few helmets, this one feels the best. It's super comfortable from out of the box. Mine was obviously one someone had returned (box was taped back together and logo was peelig off). It also sits higher on your head than most others I've tried.

    • 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. ... show more

    • Good hard shell
Size: Medium/Large Color: Denim
I used the previous gen Half Dome for the last four years. It got heavily abused - many hundreds of big days cragging, doing first ascents, being jammed into a pack with 40 pounds of gear, etc. During all that I burned through 8 ropes, three harnesses, a pile of draws and gear (and countless TC-Pros, ouch). But the helmet held up great, finally the hard harness straps are getting a bit bent and kinked. I replaced it with this current generation, and so far I'm very happy with it. In several respects I like it better than the old model - the harness is more stable, the straps don't pinch the ears, and it has a bit more ventilation. I like the way it rides and when I'm climbing I forget I have it on. It's too early to know how it's going to hold up to my abuse, but it seems very quality and rugged. Half Domes are a bit on the heavy side but I've not seen a light helmet I'd trust to take the trashing I give them. BTW, this new helmet weighs 1/2 oz more than my old Half Dome according to my scale. Like the old Half Dome the shell is pretty thick and I have confidence it will resist penetration by pointy things. ... show more

    • Protection for your Noggin
Size: Medium/Large Color: BD Orange
I bought this helmet to protect my head in case I would fall while hiking. I recently started taking blood thinners. On a recent hike, my foot slipped and my knee hit a rock, not really all that hard. Due to being on the blood thinners, my knee really swelled up. After five weeks it's still not back 100%. My doctor suggested I stop hiking, which I do for landscape photography. I asked if wearing some protection on joints and my head would be OK. "It will help." So I looked around and found this helmet. Black Diamond makes quality products. I use their trekking poles and love them (except for the tips which keep falling off). Yes, I look like a dork hiking on trails with it on. But better look like a dork than not use and hit my head, which could really be bad for me. It fits very well. There is a tightening mechanism in it so you can customize your fit. I think it would provide adequate protection. It does seem to get warm inside though. I'd recommend them for what I do. I can't talk about protection for rock climbing though. ... show more

I bought this to use mainly for high ropes courses and giant zip lines. I was happy about the reasonable pricing and decent shipping speed. Black diamond is an industry leader in protective helmets so I knew the quality that I was getting when I made the purchase. Fit is comfortable and fully adjustable to get a dialed in fit. Love the caution orange color way. It also comes with mounts for accessories. It’s also really light and comfortable. The only cons that I had is with the seller. This brand new helmet shipped covered in what appeared to be climbing chalk all over it and the box it was in. It also has a white mark on the rear of the helmet that was present and I have yet to find something to remove it with. If I didn’t need the helmet for an upcoming trip I would have sent it back to the seller. If a supposed new helmet isn’t in a completely new state then it shouldn’t be sold on Amazon. Very poor seller to ship this helmet out to a customer in this condition. I’d recommend the helmet but not the specific seller. ... show more
