Abstract

Abstract A structure is provided which absorbs shock by the controlled transfer of air from within an enclosure to outside the enclosure. A core of open-celled foam material is provided to act as an exhaustable reservoir of air within the enclosure. This structure is adapted to provide comfort and freedom of movement to the wearer. Cooperatively arranged with this structure are one or more inserts positioned to provide exceptional protection to one or more selected areas of the wearer's body. These inserts are designed to not loose shock absorbing capability when subjected to forces of anticipated magnitudes. Thus, protective equipment is provided which yields general protection to at least a portion of the wearer's body while providing exceptional protection at selected areas of such individual's body.
