1. A method of forming a grip surface of a glove, the method comprising:
dipping a glove mold into a coagulant material;
dipping the glove mold into a nitrile coating formulation to form an outer surface of the glove, wherein a biodegradable material is distributed throughout the nitrile coating formulation;
vulcanizing at least the outer surface of the glove to form a protective outer surface;
washing at least the outer surface of the glove with an enzyme solution;
decomposing, by the enzyme solution, the biodegradable material that is distributed throughout the outer surface of the glove, thereby forming a grip surface of the glove comprising an open-cell structure within the outer surface; and
drying the glove to form a final glove comprising the grip surface.
