Black Diamond


My vote: None ( 4.6 avg )


Providing ultralight, low-profile protection, unparalleled ventilation and a secure and super-comfortable fit, the Black Diamond Vapor helmet is a go-anywhere cragging lid that proves helmets aren't just for multi-pitch trad climbs and big alpine faces. We engineered a sheet of Kevlar and a series of carbon rods in between co-molded EPS foam and a polycarbonate shell to keep the weight at a minimum while keeping you protected. The Vapor's ratcheting suspension tucks into the helmet for compact storage in your pack or haul bag, and removable headlamp clips secure your light on pre-dawn starts or when rapping after dark.

Co-molded EPS foam with polycarbonate shell is lower profile than the Vector
Geometric, open-air design provides unparalleled airflow
Ratchet adjuster with molded push buttons
Headlamp clips are removable for reduced snagging on slings and clothing

Quick Adjust

Quick Adjust refers to the straps of the helmet. Do you want the ability to ability to "quickly" adjust the fit. This could be a dial, or other plastic pieces.

Really, most climbers don't need to change the fit of the helmet often, unless you're climbing with and without hats, or you have big hair that flattens and then requires tightening after climbing for awhile.

The main climbing gear certifications are CE and UIAA--and normally the UIAA creates the rules that the CE body also supports. When possible, we try to list all the certifications the product carries.

To sell a climbing product in Europe, the device must be CE certified. There are no official requirements to sell climbing gear in the US. The UIAA certification is a voluntary process.

Love how it looks and it's super comfy and breaths well. It dents very easily however, and it's expensive.

A Mountain Journey Gear Review no rating given just a review

The Black Diamond Vapor Helmet is at home climbing sport or trad, picking away at ice, climbing remote peaks, and even ski mountaineering. It’s comfortable, breathable, and ultra-lightweight. I think it’s one of the best helmets currently on the market, even though it is expensive.

Outdoor Gear Lab Gear Review rating 5/5

The Vapor is a very well ventilated helmet that sacrifices durability and adjustability for weight savings. It is expensive and offers almost no advantage over other slightly less expensive helmets.

Rugged Innovations Gear Review no rating given just a review

The construction of the helmet is fairly unique as well. The outer layer is composed of two sheets of Kevlar -- the same stuff that bulletproof vests are made with. Below the Kevlar layers you have a polycarbonate shell that holds the Expanded Polystyrene (EPS) foam. The foam itself contains a matrix of carbon rods for stability and strength. Given all the technology jammed in this headgear it's pretty remarkable that it only weighs 6.6 ounces. When you're wearing the helmet it feels thin, not bulky or dense -- and it certainly doesn't feel like there's a four-ingredient sandwich of protective tech on your head. An interesting note is that the Black Diamond Vapor passed the CE safety rating tests but did not pass the UIAA tests. I am not sure this is practically important, but I am curious why BD didn't spring for the extra material/R&D to make it pass. However, they have correctly assumed that I just don't really care that much.

The clever construction of the Vapor Helmet allows the lightness to be achieved. A combination of Kevlar, carbon rods and EPS foam all covered in a polycarbonate shell, means that the helmet is strong but actually fairly robust for a helmet of this type. I’ve actually cracked other similar lightweight EPS/polycarbonate designs dropping my pack on the ground (careless I know)! The only downside of this clever construction is that it hikes up the RRP and at £120, the Vapor Helmet is not cheap. But what price would you put on your own head?

The Vapor features an EPS foam liner molded into a polycarbonate shell. You'd expect a featherweight helmet like this to sacrifice something, but we're still searching. The fit is perfect, low-profile and over the ears. A ratcheting crown band has these very cool pinch-grips that allow you to tighten or loosen with no screwing around - seriously, you have to try it. Once on the Vapor has the best feel of any climbing helmet we've ever worn, more like a very expensive biking helmet.

Climber Gear Review no rating given just a review

In use, what can you say? Most of the time you don’t know it’s there; it's incredibly comfortable due to its light weight and the ventilation works well; certainly much better than the first generation lightweight helmets like the original Petzl Meteor. In fact, a friend recently suggested you could quite happily wear it on the walk-in using it as an alternative to having to take a sun hat, it's that unobtrusive.

Splitter Choss Gear Review no rating given just a review

I’ve been using it all year, and can say it’s by far the most comfortable and well ventilated helmet I’ve ever worn. A couple things to note, this is not a good choice for alpine climbing, as it’s not designed to take a repeated, large impacts. For sport and trad cragging however, it’s hard to beat. Also, it’s a bit pricier than other models, at $140, so you’ll have to decide if the added cost is worth giving yourself one less reason to not wear a helmet. Retail is $139.95,

Rock and Ice Gear Review rating 5/5

My concern is durability. At nearly $140, the Vapor is the most expensive helmet made, and the one most likely to get dinged up. Already, mine has a nice dent from when I tossed a pair of crampons on top of it. If you are rough on gear this probably isn’t the helmet for you. Lack of a UIAA certification is also something to think about. While the Vapor passes the CE tests, the UIAA requires that the maximum force transmitted to your head be 2 kN less. In the real world I don’t know if this would make a difference, simply because there’s no body of data about helmet use, accidents and injuries.
Black Diamond says that they made the Vapor light and low-riding because they wanted a helmet that climbers would wear all the time. To that end they have succeeded. Until now I’ve never worn a helmet for rock climbing. The Vapor has changed my ways.

Climbing Gear Review

“Cobbles fly at the Minimum Crag in Utah’s Maple Canyon,” reported one tester, “but most climbers don’t wear a helmet for fear of losing style points and because it gets hot. But the Vapor is so light and low-profile, I kept it on climbing and belaying.” The Vapor has a featherlight expandedpolystyrene (EPS) foam body layered under a polycarbonate shell, with a sheet of puncture-resistant Kevlar as well as carbon rods in between the plastic and the foam. This creates a fully CE-certified helmet at the scant weight of 6.6 ounces—even with a fully adjustable, rigid suspension system. That system completely tucks away to take up less space in the pack, a feature that all testers loved. With 20 vents, testers felt it was too exposed for ice or alpine climbing, but sport and trad climbers loved it for warm-weather sending.

The UIAA equipment standard provides a baseline for equipment performance in a test lab under controlled conditions on new equipment. Although these test conditions are relevant to the conditions encountered climbing, conditions encountered at the crags and the condition of the equipment are equally important. This recommendation from the UIAA member federation The British Mountaineering Council (BMC) provides vital equipment information that is NOT explicitly addressed in the standard, particularly failure modes of the equipment and recommendations for the use, inspection, maintenance, and retirement of equipment.
