The Petzl VERTEX VENT is ideal for rope access and tech rescue. Its medium weight design allows for stout protection without tiring the neck of the wearer. Petzls PIXA series headlamps snap right into the forward crown of the helmet, and Petzls VIZIR face shield can also be seamlessly integrated into the helmet. Rounding out the design, there are slots to accommodate hearing protection, and clips for headlamps aside from the PIXA line. Certified to ANSI Z89.1 for Type I helmets, the VERTEX VENT also features close-able slats for shutting the vents if rain or other small falling debris becomes an issue.
