Abstract
A face mask is provided. The face mask includes a body portion that is configured to be placed over a mouth and at least part of a nose of a user such that the air of respiration is drawn through the body portion. The body portion includes a baffle layer which helps prevent penetration from a fluid striking the mask. The baffle layer has an outer and an inner surface with a plurality of projections extending from one of the outer or inner surfaces. The baffle layer aids in absorbing energy associated with fluid striking the body portion of the mask. The baffle layer distributes fluid away form the point of impact in the channels between the projections.
