Claim:
A roll for use as bathroom tissue, formed of a rolled strip of a cellulose-fiber product, said strip comprising: at least three superposed and associated plies, said strip having a tensile strength R ST across its width ( 1 ) such that a product P of the total thickness E of the strip times its strength R ST is greater than a value obtained when a thickness of 0.75-1.5 mm is multiplied by a tensile strength of 200-500 N/m, E being expressed in mm and R ST in N/m, wherein: at least one of the plies comprises one of a wet pressed ply or a through air dried ply, another one of the plies comprises the other one of the wet pressed ply or the through air dried ply, and an exterior one of the plies is formed with a first pattern including a repeating pattern of deep and shallow angular cross-sectional shapes and the other exterior one of the plies is formed with a second pattern including a repeating pattern of shallow wavy cross-sectional shapes.
