Wall Rider MIPS Helmet
Mammut
The Mammut Wall Rider MIPS brings advanced rotational-impact mitigation into technical climbing terrain. Climbing helmets have traditionally guarded only against straight-line linear impacts from falling rock. By integrating a MIPS (Multi-directional Impact Protection System) low-friction layer, this helmet allows 10 to 15 millimeters of relative movement during angled impacts, significantly reducing rotational forces transferred to the brain during awkward, tumbling falls. The helmet’s foundation is an ultralight EPP foam body capped with a robust hard-shell plate across the top. This hybrid geometry ensures reliable deflection of jagged overhead rockfall while keeping total weight between 7.9 and 8.8 ounces depending on shell size. A minimalist webbing adjustment system secures the base of the skull, and large cutouts along the sides and rear maintain airflow on strenuous pitches. Price and fit customization are the chief considerations. The addition of the MIPS slip-plane elevates the cost significantly above standard climbing helmets. Moreover, the minimalist webbing harness, while effective at saving pack space, lacks the instant micro-adjustability of a traditional plastic dial wheel, requiring precise manual strap fitting before setting off up a wall. **Highlights** - Integrated MIPS rotational impact protection layer - Lightweight shock-absorbing EPP body with hard-shell crown plate - Excellent vent layout for high-output climbs - Compact webbing cradle reduces pack volume - Reinforced front clips for headlamp attachment **Watch-outs** - Premium pricing driven by MIPS technology - Webbing suspension requires deliberate manual adjustment

Boreo
Petzl
The Petzl Boreo is built for maximum durability, utility, and cost efficiency. Serving as Petzl’s primary hardshell workhorse, the Boreo utilizes a thick ABS shell supported by a hybrid foam liner composed of both EPP and EPS. This makes it an ideal helmet for gym-to-crag climbers, institutional groups, and mountaineers seeking complete dependability without spending top-tier prices. Where the Boreo excels is overall coverage and daily resilience. It incorporates Petzl’s rigorous top-and-side protection design, dropping low around the ears and back of the head to defend against low-angle rock bounces and uncontrolled leader falls. Its thick ABS shell is practically impervious to the dings and squashing forces of stuffed backpacks, making it an excellent piece of kit for climbers who prefer not to baby their gear. At 10.6 ounces, the weight is noticeable when compared directly against hybrid foam models. The internal ventilation ports are smaller than those on higher-end helmets like the Meteor or Vision, resulting in a warmer microclimate on mid-summer ascents. However, for rugged durability at roughly $75, the trade-offs are entirely defensible. **Highlights** - Ultra-durable ABS outer shell resists rough handling - Hybrid EPP and EPS foam liner for enhanced energy absorption - Comprehensive side, rear, and top impact coverage - Simple, glove-friendly rear adjustment system - Accessible price point around $75 **Watch-outs** - Heavier profile at 10.6 ounces - Limited ventilation makes it run warm in direct sun

What our reviewers liked and didn't
Wall Rider MIPS Helmet
- Integrated MIPS liner reduces rotational forces from angled climbing impacts.
- EPP foam construction resists minor handling bumps better than pure EPS.
- Hard-shell crown plate provides dependable deflection against falling debris.
- Webbing harness packs flat, taking up minimal volume inside a climbing pack.
- Substantially more expensive than standard climbing helmets without MIPS.
- Webbing adjustment lacks the fast micro-tuning of a traditional dial wheel.
- Exposed lower EPP foam can get scuffed or gouged by careless packing.
Boreo
- Thick ABS shell withstands rough pack transit and sharp debris without denting
- Hybrid EPP and EPS foam liner provides thorough lateral and rear protection
- Collapsible headband system packs down smoothly inside the helmet bowl
- Exceptional long-term durability at an accessible retail price point
- At 10.6 ounces, it feels heavy compared to modern all-foam alternatives
- Modest vent openings trap heat during high-exertion climbs in direct sunlight
