It has been more that 6 months that I have been researching for a new helmet that I would be using for my outdoor adventures. I have been looking at all different kind of helmets and of course from various brands. My requirements for a new helmet were rather specific and the activities I would be using it are mainly alpine climbs, winter mountaineering and climbing activities. Therefore, I wanted to have a rather lightweight helmet that would be comfortable to wear all day long. My final choice was to purchase the Mammut Wall Rider.
