Petzl A73 Sirocco Helmet – Ultra-Lightweight & Durable Climbing Protection
Ultra-light polypropylene shell with expanded foam core for maximum impact absorption, weighing only 175g for fatigue-free endurance. Laser-cut ventilation channels optimize airflow during intense ascents, reducing heat buildup on multi-pitch climbs or alpine routes. Low-profile ABS polymer reinforcement around critical zones ensures durability against rock scrapes and gear impacts. Hybrid construction combines hard-shell toughness with foam-core comfort, certified for UIAA/CE standards in rock, ice, and via ferrata. Modular webbing system with tool-free adjustments fits over beanies or headlamps, ideal for fast-and-light alpine missions. Compact foldable design stows easily in pack side pockets for approach hikes or expedition logistics. Exclusive Petzl thermo-welded seams eliminate stitching failure points, tested for extreme humidity and sub-zero conditions.
