Petzl BOREO Gray Helmet

The Petzl Boreo helmet is a unisex model designed for climbers, mountaineers, via ferrata enthusiasts, cavers, and canyoners who are looking for rugged protection without compromising on versatility. Its hybrid construction, combining a thick ABS shell with EPP and EPS liners, provides impact and scratch resistance suitable for demanding environments. Its full-coverage profile, which is lowered at the back, sets this helmet apart from the more open models on the market.

THE BOREO GRAY M/L HELMET: Comprehensive Protection on All Sides

The Boreo’s design meets precise specifications for protection. Petzl’s TOP AND SIDE PROTECTION label certifies effective coverage against side, front, and rear impacts—areas where many climbing helmets are limited to top-of-the-head protection alone. This protective geometry is directly linked to the helmet’s lowered profile at the back of the head—an area often exposed to falling rocks or debris on the rock face. The helmet meets CE EN 12492, UKCA, and UIAA certifications, which are recognized standards for mountaineering and climbing equipment. These certifications attest to a level of compliance with current safety requirements, though they do not guarantee absolute protection in all situations.

A Fit Designed for Real-World Use

The Boreo features an adjustment system for the side straps and chin strap, allowing for precise adjustment to fit each user’s head shape. The M/L size weighs 330 g, a measured value that reflects the balance achieved between the shell’s durability and comfort during extended wear. The helmet’s optimized ventilation helps limit heat buildup during sustained exertion. Two hooks at the front and an elastic strap at the back allow a headlamp to be attached directly to the helmet—a useful feature for caving trips or nighttime approaches in mountaineering.

Practicality and Easy Storage

The retractable headband is one of the Boreo’s practical features: it reduces the helmet’s volume, making it easier to carry in a backpack or store between outings. This feature is particularly valuable for mountaineers and climbers who carry their gear on long approaches. The polyester straps round out a design built to last in a variety of conditions.
