Wall Rider 2.0
Mammut
The Mammut Wall Rider 2.0 is an ultralight minimalist helmet designed for alpinists and climbers who want maximum weight savings without moving entirely away from a hard top cap. Weighing roughly 6.3 ounces in the smaller size, it relies on a sculpted expanded polypropylene (EPP) chassis reinforced across the crown with a hardened shell plate to ward off falling rock and ice debris. Real-world performance mirrors its fast-and-light pedigree. The EPP foam base acts as an elastic, shock-dampening shell that absorbs glancing blows and easily survives tight packing in mountaineering rucksacks. The helmet features generous ventilation channels across the profile, keeping the climber cool during lung-busting alpine approaches. The suspension utilizes minimalist webbing straps that reduce bulk and fold neatly inside the shell. The trade-offs stem directly from its lightweight design. While the hard crown plate provides security from above, the exposed EPP foam flanks remain unprotected against scrapes, sharp metal gear, and abrasive rock surfaces. The webbing adjusters also take more manual fiddling to dial in compared to simple ratcheting dial wheels. **Highlights** - Exceptionally light at approximately 6.3 ounces - Shock-absorbing EPP body with rugged hard-shell crown cover - Large ventilation ports for superior airflow on hot routes - Minimalist webbing harness folds flat for packability - Dependable headlamp attachment clips **Watch-outs** - Exposed side foam susceptible to surface gouges and abrasions - Webbing harness requires two hands to fine-tune fit

Vision
Black Diamond
The Black Diamond Vision is engineered for climbers who want the low weight of an ultralight foam lid without sacrificing structural resilience. Built around an expanded polypropylene (EPP) body with a strategic expanded polystyrene (EPS) puck and a thin polycarbonate crown cap, the Vision offers full side and back protection while deflecting top-down rockfall. Review consensus ranks it among the most comfortable, well-ventilated helmets available, making it equally adept on sweltering multi-pitch trad routes or high-altitude alpine objectives. In real-world use, the helmet’s harness system stands out for its low profile and intuitive fit. The webbing adjusts smoothly and folds cleanly into the interior, allowing the helmet to pack down without snagging or breaking adjustment ratchets inside a loaded haul bag. Broad ventilation ports promote airflow on warm approaches, and the shell geometry sits low enough to ensure genuine rear-head coverage without obstructing the climber’s upward field of view. The trade-off comes down to cost and exposed foam durability. At around $160, it represents a substantial investment. While the polycarbonate top cap protects against overhead impacts, the exposed EPP foam along the perimeter can still suffer cosmetic gouges, dents, and abrasions if lashed carelessly to the outside of a heavy pack. **Highlights** - EPP foam construction with EPS puck and polycarbonate top cap - Low-profile suspension system that packs flat - Generous venting along sides and rear - Low-profile headlamp clips with elastic rear strap - Exceptional weight-to-protection ratio at 7.6 ounces **Watch-outs** - Exposed EPP foam on sides can pick up cosmetic dents - Premium price point compared to standard hardshell helmets
