The Crag Sender Helmet by Mammut is designed for use on rock. This lightweight and well-ventilated climbing helmet not only impresses with its comfort but also offers a high level of safety. Thanks to its Inmold construction, it is both robust and lightweight. Reinforcements made of Kevlar ensure that it is particularly durable and can withstand strong external impacts. The practical adjustment mechanism at the back of the head, along with the fully adjustable chin strap, ensures that the helmet fits perfectly and does not wobble. Strategically placed padding also helps prevent pressure points. On warm days, the generous ventilation is a significant advantage, with several large ventilation openings connected by a ventilation channel allowing for quick temperature regulation.
