The two or more porous webs comprise woven or non-woven materials and the resulting breathable fabric or laminate has good hand and flexibility. Breathable fabric is adhered to foam by such random fibrous adhesive patterns of similar coat weights. Coating widths of up to 80 inches or more are produced in a slot die fed by a selected plurality of recessed lands within the die, with motors and pumps controlled to maintain consistent, uniform coat weights regardless of coat widths and substrate speeds selected. Single ply coated webs, apparatus and methods are disclosed.
