A one-piece first shock attenuating member is positioned adjacent to and in substantially in contact with portions of the interior surface of the shell. The first shock attenuating member has a first thickness and a first compression deflection. A plurality of discrete second shock attenuating members are positioned adjacent to portions of the first shock attenuating member and adjacent to and in substantially in contact with portions of the interior surface of the shell. Each second shock attenuating member has a second thickness and a second density, with the second thickness being greater than the first thickness and the second compression deflection being less than the first compression deflection.
A helmet for wearing on a cranium of a user, the helmet comprising:
A helmet, comprising a shell having a rear portion and opposite side portions having ear holes and an offset defined on a substantially continuous portion of the shell extending between the rear and opposite side portions for increasing the flexural resistance of the shell, wherein the offset extends substantially between the ear holes.
