I'll start this by saying this helmet is mediocre. It is outrageously overpriced for the cheap black foam its made of, and it didn't reach the same level of certification as other helmets so it really is not as safe. Additionally, coworkers have cracked the strips of foam between vents through basic use and abuse. On the other hand, it looks pretty sexy and is quite light. For skimo races attach your goggles with zip ties and you have a great skimo helmet as long as you don't hit your head!

This is a great light weight helmet but you can not use goggles with it. There is no place to secure your goggle strap at the back to keep the strap from falling down to your neck. When I called Black Diamond to suggest a fastener system to make the use of goggles possible I was basically scolded by a rep there saying the this helmet is not rated for skiing so therefor they had no plans to create a system to make the helmet goggle compatible. So they are very clear that it is not a ski helmet. I attempted to create my own loop on the back to secure my goggles strap but got frustrated. It just will not hold a goggle strap in the back so I sold my helmet.

Overall: Five Stars for an absurdly light helmet that doesn’t make you look absurd. Only notable reservation is eyewear fit.

Background on product familiarity: I bought my Vapor helmet in Spring 2013, and have worn it since for lots of training, racing, and “real” touring.

First, the first impressions out of the box: Even compared to almost all the very light bike-style climbing helmet competition, the aptly named Vapor is noticeably lighter. Plus the material is relatively thin on top, and the helmet extends down relatively far on the sides, so the Vapor has no alien-style “crystal dome” effect (especially compared to the downright embarrassing Petzl Sirocco).

The ratcheting adjustment in the back is simple and effective, and ditto for the chin strap. Fit matches up well with the sizing chart.

Second impressions, in use: Since the Vapor comes down a little more than other climbing helmets, some sunglasses with relatively high corners don’t fit well. For ski goggles, I’ve never tried using the headlamp clips, although alternatively, with all the vents to serve as attachment points, jerry rigging would be easy with some combination of zip ties, resort lift ticket holders, and/or velcro straps. And those headlamps clips are removable, so if you ever do remove them (or don’t attach them in the first place), remember to snap them on before any outing where you might need them!

Third impressions, for long-term durability: All bike-style climbing helmets are designed to sacrifice their lives for you. But many reviews of the Vapor question its durability from just being carried about, although I’ve never read of any failures. I did shred the interior padding relatively quickly, but Black Diamond sent me an easily swapped-in replacement.

Light, comfortable, and secure-fastening. What's not to like? Well, to be fair, I'm not 100% sold on the durability and protectiveness it offers. If it wasn't so unwearably fugly, the Petzl d***helmet bests both durability and weight of the Vapor, for which I'm deducting a star. IMO it should extend further down the occipital area for better protection.

It would worthwhile investigating whether this helmet would actually be allowed at World Cup level competitions, or any other ones that strictly follow ISMF rules. I have this feeling because few years back ISMF was forbidding helmets with lots of vents like on this one with the reason being that should you end up in an avalanche then snow would fill those big vents and effectively serve as an anchor. This was actually supported/proposed by UIAA standards I believe. Also, I haven't see this helmet on World Cup photos so that's why I am not sure (but I might have missed it).

Anyway, if planning to compete outside of NA with this or any helmet, check with ISMF rules/office if it's approved.
