SAFETY ON STEEP TRAILS Steep climbs, high-speed racing, all-day adventures: "Down-country" may be an industry buzzword, but it's what so many riders have always done. Down-country is all about going up fast, down fast and repeating. The Moventor 2.0 is ideal for the demands of mountain bikers who feel at home on steep trails. The MTB helmet is lightweight, well ventilated and has a deeper fit that gives more protection at the back of the head. When the trail points downwards, the 10 air inlets and 9 air outlets provide good ventilation. Thanks to the Zoom Ace MTB adjustment system, the helmet can be individually adapted to your head. This is especially important when you ride off-road. What more do you need?
