A protective material/structure is provided that reduces the risk of injury for a person after contact with said material/structure, and is based on a structure where an inner and outer shell can move relative to each other. The shells are separated by spikes or thin beams and the outer shell covers or envelops the spikes. The spikes or beams are constructed so that they permit displacement of the outer shell relative to the inner shell in the event of an oblique impact against the protective material/structure. The spikes or beams are designed to be thin/slim and can be made of flexible polymer materials such as plastics, rubber or fibers. This enables the spikes to give way after a tangential/rotational impact and thereby efficiently reduce the negative effects of such an impact on the brain. The material/structure can be used in e.g. helmets, vehicle interiors, vehicle exteriors, indoor house building material, boxing gloves and the like.
