The Petzl Altios is part of a new breed, that of the hybrid helmet - the use of a combination of expanded foam liner and a mesh panel making it both comfortable and lightweight.
This innovative design has the affect of giving the helmet a near weightless feeling, and in addition, the space created between the head and the liner allows for efficient ventilation to help keep you cool and dry.

Petzl: How It All Began
Fernand Petzl made the first 1,000 metre cave descent in France in 1950, laying the foundations for vertical safety technology of the future.
Twenty years earlier he had started working with fellow speleologist Pierre Chevalier, making new advances into the basic thinking behind their shared sport.
Fast forward to 1975, and the Petzl corporation was born at the base of the Dent de Crolles – Crolles’ Teeth – near Grenoble, heralding an era of innovation and design which brought us the Grigri belay device, Tikka and Tikkina head torches, and a range of safety helmets and harnesses used by cavers and climbers all over the world.
Renowned throughout the industry for their ‘work-at-height’ products and highly-technical rescue equipment, Petzl have expanded their manufacturing line to include specialist ice climbing technology, and are committed to raising social, environmental and ecological awareness - alongside research into risk prevention - of all mountaineering sports.
