Abstract
Abstract A non-slip material used, e.g., as a handle grip covering provided for replacing the usual material wrapped around the handle of, for example, a golf club or tennis racket. The material may be used to cover any surface where non-slip is desired. The covering comprises a substrate coated on one side with a foamed material comprising, for example, a vinyl copolymer resinous binder containing expanded microspheres. A wax coating covers the foamed material coating. This handle covering is wrapped around a handle. It provides a non-slip, perspiration absorbing handle cover.
