Details Black Diamond Vector Helmet A revolutionary helmet that's ideal for long routes, alpine climbs and other weight-sensitive missions, the Black Diamond Vector helmet combines lightweight protection, excellent ventilation and "barely there" comfort like never before. The geometric, co-moulded EPS foam and polycarbonate shell provides full-coverage protection while remaining incredibly lightweight and comfortable. Generous ventilation ports keep the air flowing on warm days. The ratcheting suspension tucks away for easy storage in your pack, and when the sun gets down before you do, the Vector's in-mould headlamp clips provide an ultra-secure attachment. strong>Weight: [S/M] 231g[M/L] 240 g Size Range: [S/M] 53-59cm[M/L] 58-63cm (23-25 in) Co-moulded EPS foam with polycarbonate shell Large ventilation ports provide max airflow Ratchet adjuster with moulded push buttons In-mould headlamp clips for ultra-secure attachment Tuck-away suspension makes for compact storage Specifications Vector Helmet
