The Boreo® is a robust helmet for optimal protection on all your adventures! The Boreo® is suitable for climbing, via ferrata, canyoning and speleology. The thick outer shell makes it particularly resistant to impacts and scratches. The enclosing helmet shape protects your head even better, while the compact and ventilated design ensures maximum comfort. The hybrid construction with a thick outer shell of ABS, an inner shell of EPP foam and an inner shell of EPS foam ensures a compact fit on the head. A head-hugging design, lowered in the neck area, provides increased impact protection on the sides and in the front and back of the head. Petzl - Boreo\u00ae Climbing Helmet grey
