Black Diamond Vector Helmet on the rock
The Black Diamond Vector Helmet is a lightweight climbing helmet built for alpinists and rock climbers who demand serious protection without added bulk. Constructed using a hybrid shell design, it combines an injection-molded polycarbonate exterior with an expanded polypropylene liner, delivering both top-impact and side-impact protection while keeping the overall weight remarkably low. At just around 245 grams, it disappears on your head during long approaches, technical pitches, or multi-day alpine missions where every gram counts.
Ventilation is a standout feature of the Vector, with strategically placed air vents that promote airflow and reduce heat buildup during strenuous climbs or warm-weather outings. The adjustable harness system allows climbers to dial in a secure, comfortable fit across a range of head sizes, while the low-profile design ensures compatibility with climbing packs and headlamps without shifting or bouncing around. The four-point chin strap and easy-to-use buckle add another layer of security, letting climbers move confidently through exposed terrain, rockfall zones, or steep ice without worrying about helmet stability.
Durability is built into every aspect of the Vector's construction, making it a reliable choice for trad climbing, sport climbing, mountaineering, and via ferrata routes where rockfall and overhead hazards are a constant concern. The helmet meets rigorous safety certifications for climbing equipment, giving users peace of mind on committing routes. Its versatile color options and streamlined profile also make it a practical everyday choice for climbers who want dependable head protection that integrates seamlessly into their kit without sacrificing comfort, breathability, or performance on the wall.
