Abstract
Abstract A low cost disposable pair of training pants formed substantially entirely of paper. These pants include an outer paper sheet that defines the waist opening and leg openings, and an inner paper liner secured to inner surfaces of the outer sheet. The liner is selected for its water absorbency characteristics. The outer sheet may be selected primarily for its strength and flexibility.
