Abstract: An American-style football may include a prolate spheroidal shaped bladder having a longitudinal axis, an outermost layer about the bladder, a lacing surface featuring a series of parallel projections from an exterior of the outermost layer and an intermediate sandwiched between the bladder and the outermost layer, wherein the intermediate layer is configured to decrease a MOI of the football.

Abstract: A golf club may include a head having a body and a faceplate coupled to the body. The faceplate may have a maximum thickness at a central location and a cross-section intersecting the central location. The cross-section may have continuously variable wall thickness across the faceplate. The faceplate may have a closed non-convex contour curve defined by constant faceplate wall thickness that encloses the central location.

Abstract: A golf club includes a face coupled to a body. A composite axis extends from a heel to a toe of the club and parallel to ground. The face is formed of a fiber composite material including at least first and second sets of ply arrangements. Each of the ply arrangements includes a pair of plies having first and second pluralities of fibers defining first and second angles with respect to the composite axis, respectively. The face has a ball contact surface, an rear surface, and a mid-zone positioned equidistant between the contact and rear surfaces. A majority of the first and second pluralities of fibers of the ply arrangements between the mid-zone and the contact surface are formed of glass fibers, and a majority of the first and second pluralities of ply arrangements between the mid-zone and the rear surface are formed of carbon fibers.
