Review: Great helmet, horrible desertcart 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 desertcart, 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. desertcart 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.
Review: Nice - Got this as a bike helmet , it’s a great helmet and has adjustments

## Questions & Answers

**Q: Size guide?**
A: Hello,

Please see sizing below.

Small/Medium	                Medium Large
48-57cm / 19-22.5in	       55-61.5cm / 22-24in

**Q: Is this ansi and or osha approved?**
A: Not sure about ANSI or OSHA. Best bet is to contact Black Diamond directly and ask if the compliances met already on the helmet encompass the ones you are asking about. Here is what the instruction manual indicates: 

EN 12492: This number indicates that this helmet conforms to EN 12492:2012, the
European Standard for “Mountaineering equipment – Helmets for mountaineers –
Safety requirements and test methods.”
UIAA: The presence of the UIAA Label indicates that the helmet has been tested
according to UIAA 106 and awarded the UIAA Safety Label.
 : The CE mark of conformity indicates fulfillment of the requirements of the
Personal Protective Equipment Directive (89/686/EEC) or Personal Protective
Equipment Regulation (EU 2016/425).

**Q: How well would this helmet protect against falling rocks from above? Is it as strong as an industrial hard hat?**
A: Compared to a hard hat, I’d think this helmet offers more protection. Of course, its safety depends upon the size of the rocks and the distance it falls.

**Q: Is it possible to separate the plastic from the hardware/foam in order to change out the shell color or paint the shell?**
A: The components of this helmet are not meant to be separated (with the exception of the foam comfort padding), and we cannot recommend any modifications to protective equipment.

Got this as a bike helmet , it’s a great helmet and has adjustments

### ⭐⭐⭐⭐⭐ my helmet isn’t just part of my gear — it’s my lifeline
*by M***N on August 12, 2025*

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.
