Durable and versatile helmet with reinforced protection for climbing and mountaineering.

Durable and very versatile, the BOREO helmet is suitable for climbing, mountaineering, caving, via ferrata, canyoning... Thanks to its hybrid construction, the helmet is both compact and head-covering. Protection against lateral, front and rear impact is reinforced. Optimized volume on the head and wide ventilation holes make it a comfortable helmet for all activities.

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.

Boreo Helmet Review

No reviews yet.

Evening Sends Gear Review no rating given just a review

If you’re looking for one do-it-all climbing helmet that will hold up to lots of mileage and give you an extra piece of mind about protection from rock fall as well as taking sideways whippers when you break a hold unexpectedly, you’d be hard pressed to find a better solution than the Boreo.

Blister Gear Review no rating given just a review

The Boreo is an affordable, comfortable, durable, helmet that offers the additional piece of mind of passing Petzl’s side protection tests in addition to UIAA and CE testing standards. It’s not the lightest option out there, but if you’re looking for an everyday helmet that offers increased protection from side, front, and rear impacts, the Boreo is definitely worth a look.

Northeast Alpine Start Gear Review no rating given just a review

The Petzl Boreo is the most durable and protective climbing helmet I have reviewed to date. The focus on increased side and rear impact protection is proof of Petzl’s forward thinking design and desire to not only meet existing standards but go beyond. The Petzl Boreo is a great choice for not only rock and ice climbing but for ski mountaineering pursuits. While ounce counters might not like the relatively high weight those looking for value in a long lasting highly protective helmet wouldn’t find many options as appealing as this one. I think this is an excellent choice as a “first” helmet and its durability will likely keep it in your kit for certain missions throughout your climbing career.

Rock and Ice Gear Review no rating given just a review

Typically, I’m a medium in just about everything, but I am a M/L in the Boreo (size options are S/M and M/L). If you’re unsure, size up, which also guarantees that you can get a beanie under there in colder temps. Adjusting the helmet is intuitive and easily done while it’s on your head, or, assuming you’ve got a no-hands rest, when you are on route. A pet peeve of mine is when the side straps dig into your ears. Thankfully, the Boreo’s straps were barely noticeable. Sleek headlamp clips adorn the front and rear, and with ten ventilation holes, it breathes. Lateral protection is ample, and its rear drops down to the concave back part of your skull. Inside, the liner pads can be unvelcroed for easy washing. At around $65, it’s hard to go wrong with this one.

UK Climbing Gear Review no rating given just a review

Tough, protective, comfy and well fitting, the BOREO is great value at £55. With head coverage that comes low at the sides and rear, and an impact absorbing lining right down to the rim, the amount of protection on offer inspires confidence. It's neither the lightest nor the coolest of Petzl's helmets, but while it's not the best choice for hotter weather, or fast-and-light purists, it makes up for this with durability. If you're dishing out abuse, the BOREO can take it. For me this makes it particularly good for winter use. If you're just buying one helmet for a bit of everything, from cragging to winter mountains, this would be a great choice.

Outdoor Gear Lab Gear Review rating 5/5

The Petzl Boreo is our Top Pick as the most Rugged and Protective helmet in this review. If protecting your dome piece at all costs is your number one priority, then we don't think you could find a better option. It is also affordable, reasonably comfortable, and accommodates a headlamp very well. While the very lightest helmets are tantalizing, the Boreo is one you can rely on.

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.
