The Wall Rider MIPS climbing helmet from Mammut is reliable and performing, characterized by a technical and light structure with a weight of only 220 grams. Pioneer of climbing helmets, he is the first to present the patented MIPS technology. In case of impact due to falling rocks from above or during a fall, this technology intervenes reducing the risk of brain damage. Structurally Mammut Wall Rider MIPS has a low friction inner shell positioned between the helmet and the head and optimized to absorb part of the energy generated by an impact. Thanks to this technology, during the impact, the helmet slides with respect to the head. The inner shell is in EPP while externally a hardshell layer partially protects the head in its central upper part. The large ventilation holes keep the climber's head always dry and well ventilated. Its ergonomic profile and its adjustment system ensure a perfect and secure fit at all times. Minimalist but very comfortable helmet and quickly adjustable through the adjustment straps on the back of the head and chin. For long tours you will be comfortable to attach a front to the two clips on the front and the rubber strap on the back.
