Mammut Wall Rider Review
A solid lightweight helmet that’s a good alternative to the Sirocco
Credit: Mammut
RELATED: Best Climbing Helmet of 2023
Our Verdict
The Wall Rider is Mammut's lightweight helmet made of a combination of EPP foam and a partial hard plastic top. Featuring a comfortable fit, simple yet effective minimal harness system, and plenty of ventilation, it is one of the highest overall scorers in our comparative testing. It makes for a great alternative to our Editors' Choice award winner for those who find its fit more comfortably than that helmet, likely a judgment call based on head shape. However, despite using ultra lightweight EPP foam, the advantages are a bit offset by the addition of heavier plastic on the exterior. Regardless, this is one of the lighter and more comfortable climbing helmets you can buy and one we highly recommend. It is an ideal choice for any sort of climbing day or adventure, and is also designed to be used with ski goggles as well, making it a ski mountaineering option as well.

Our Analysis and Test Results
The Wall Rider is Mammut's top of the line helmet that competes directly with other lightweight EPP foam offerings, but without offering quite the same level of comfort or light weight. We found it to fit a bit shallower on the top of the head, and to be designed to a more circular shape, that for our head tester didn't fit perfectly. This issue caused more pressure points against the top and especially back of the head, lowering its comfort score. The caveat, of course, is that comfort is relative and so what wasn't as comfortable for us may prove to be far more comfortable for you, so be sure to try both on if you are in the market for a lightweight EPP helmet. While we have awarded this helmet our Editors' Choice award in the past, we currently feel that the heavier weight, slight dip in comfort, and difficulty with the headlamp clips, have dropped it down a notch from that perch. When considering the benefits of the Wall Rider, we are more inclined to throw down an the extra cash and purchase the Wall Rider MIPS, for its brain protection technology--the reason we wear helmets in the first place. It seems worth the extra money.
Performance Comparison
The Wall Rider is an EPP foam helmet with a hard plastic shell covering that adds to its durability. It is comfortable, light, and easily adjustable, making it a great choice for any sort of climbing.
Comfort
Much like the other foam helmets we have tested, this one relies on a couple of foam pad inserts Velcroed to the inside of the helmet to act as cushioning — one on top and one across the front of the forehead. These pads can be removed and swapped out or washed if desired, but we found them to be slightly less cushy than those in some other models. As we have already mentioned, for us the fit and shape of the helmet are not absolutely perfect, with slight pressure points against the back of the head where the unpadded foam rests against our skull. For many, this will be a very comfortable helmet, and for us, it isn't overly uncomfortable, but rather doesn't quite live up to the standard set by the other competitors.
The thin black pads on the top and front of this helmet provide some comfort and padding, as well as sweat absorption. As with most helmets, the comfort level is somewhat dependent on how well the helmet matches the shape of your head. The Wall Rider is a bit shallower and rounder than the deeper and more oblong Sirocco.
Adjustability
This helmet uses a lightweight webbing harness system to hold the helmet securely in place on top of the head. The rear strap is adjustable with buckles on each side, so if you need to tighten it up a bit, you can do so in an even way that keeps the helmet perfectly centered. These straps and buckles are fairly easy to pull and tighten with the helmet on your head, as long as you know what you are trying to grab. The location of the chin strap along the v-yoke that goes around the ears is effortless to slide back and forth, and likewise, the chin strap itself is easily adjustable. This helmet does not have the adjustability range of those with a spinner wheel, or even one of the slider bar options, but is still fairly easy to adjust.
Adjusting the fit of this helmet is done by pulling on the two tabs of webbing that run through these two buckles. It is best done with the helmet on the head to nail the fit perfectly, and if you know what you are reaching for, this is rather simple.
Weight
Our size large version of the Wall Rider weighed in at 8.5 ounces. While this is fairly light, it is over two ounces heavier than the lightest option in this review. Two ounces may not seem like much when you read about it, but try both on, and you can immediately notice the difference. Even tiny weight differences like this have an impact on a long multi-pitch or alpine route, and we lament the fact that despite using the lightest EPP foam available, this helmet is still not competitive with the lightest. Those interested in the Wall Rider MIPS should know that adding that technology only adds 0.5 ounces to the weight of the helmet, so comes at only a minimal price in weight.
This is a light helmet at 8.5 ounces, although not as light as the EPP foam could be. The extra weight is due to the large and rather thick plastic shield protecting the top and front of the helmet.
Ventilation
This helmet has 16 rather large vents spread out on the sides and back, with a couple of vents in the front positioned directly over the temples. These two front vents, in particular, seem to help with cooling off the head, especially if there is a wind blowing. While you can certainly buy helmets that have even more ventilation if you choose, we still think it is one of the best at not heating up too much on a warm day.
With plenty of large vent holes on the sides and back of this helmet (and two in the front as well), this is one of the "cooler" helmets in this review. The exposed black foam is EPP, which can take more impacts than EPS without becoming permanently deformed. This saves weight, since that part of the helmet doesn't need to be covered with a plastic shell.
Headlamp Attachment
There are a couple of features to note to attach a headlamp: two clips in the front with teeth on the bottoms, combined with the single elastic bungee and hook system in the back that latches over the top of the headband. This rear bungee is also designed to work well to hold ski goggle straps in place, making this a more versatile helmet for use while mountaineering or ski mountaineering. Our one complaint is that compared to the straightforward headlamp clip designs, found on most of the other helmets, the ones on this helmet are extremely tight, and take a bit more effort to slide the strap up underneath. This tension seems pretty unnecessary considering how effectively these clips hold a headlamp in place anyway.
The dual front clips and single elastic band in the back hold a headlamp in place without concerns. However, compared to other contenders, the front clips on this helmet are very tight and harder to force the headlamp band under quickly, especially if the helmet is already on your head.
Durability
The Wall Rider is made entirely of EPP foam, known for its resiliency to taking many blows without cracking. However, for gentle everyday abuse, this foam needs protection, and this comes in the form of a large hard plastic top piece that covers the entire top and front of the helmet, but leaves the foam on the sides and back exposed. Some care is needed to keep from unnecessarily damaging the exposed foam, but we like the solidity of the top piece for allowing this helmet to take multiple smaller hits without needing to be retired.
Made with exposed EPP foam and a hard plastic shield on top, the Wall Rider is both lightweight and durable enough for long term use.
We should point out that our judgments on durability are only for daily wear and tear, and are not a statement about how well a helmet can take a direct hit from a rock or ice and be usable afterward. This helmet does meet EN standards for climbing helmets, however.
The Wall Rider is a good helmet for any sort of climbing, whether its alpine, multi-pitch, ice, or even single pitch cragging. We found it to be comfortable and light and barely noticeable on the head while attempting harder sport projects.
Value
At retail price, this helmet is a bit more expensive than the majority of lightweight helmets, although still not the most expensive one you can buy. If you are looking for a lightweight helmet and this one fits you better than those options, then we think it presents a good value. In this price range, the helmet that fits your head the best is likely going to be the best choice.
Conclusion
The Mammut Wall Rider is a lightweight, comfortable, well-ventilated helmet that should serve as a great alternative to the lightweight Petzl helmets for those who don't like the way they fit. Despite being made of EPP foam, it isn't the lightest choice, and for us, it doesn't fit quite as comfortably as some others, but we still feel it's a good lightweight option that isn't prohibitively expensive.
Nearing the summit of Mt. Hood, Oregon's tallest mountain, on a ski mountaineering mission. The Wall Rider is a great option for adventures like this because it's light and allows for wearing a beanie underneath.
