Alveo Vent Climbing Helmet
The new Alveo Vent is Petzl's lightest weight and most ventilated helmet yet. It fits closer to the skull than the Vertex and is therefore more stable and less noticeable. The new Centerfit adjustment system with two adjustment knobs ensures optimal fit and stability by centering the head inside the shell (head circumference from 53 to 63 cm). Compatible with Peltor ear muffs and Peltor wire mesh visor or clear plastic Petzl Vizir.
