Petzl Alveo Vent
A good helmet for route setting and rope access - it is the best for having all the attachment points (for visors or ears)/ headlamp clips - but still has good ventilation and not too bulky.
Ventilated helmet for work at height and rescue
Featuring a strong chinstrap, the ALVEO VENT helmet is a very lightweight helmet for workers at height. It has ventilation holes to allow the ventilation to be adjusted as needed. It is built to be lightweight and its Center Fit adjustment system adjusts the headband and keeps the helmet centered on the head. The ALVEO VENT is designed for optimal attachment of a headlamp, a protective shield, and hearing protection.
