Travelling by bike is a great way to spend your free time with friends or family. When cycling, it is advisable to wear a helmet to avoid serious head injuries in the event of an accidental fall. The Alpina MTB17 fulfils its function perfectly on unpaved roads, cycle paths and also on the road. The Alpina MTB17 is a bike helmet with an in-mould construction and 23 ventilation holes that guarantee excellent air circulation. The Shield Protect shield protects the user's vision from the sun's rays. The helmet can be quickly adjusted to individual requirements using the adjustment system and Y-clip straps.
