Abstract: A secondary layer of material on top of a portion of a primary layer of material and coupled to the primary layer of material, where the primary layer of material and the secondary layer of material defining a first sleeve passage having a length from a vertical intermediate axis of the primary layer to the side edge of the primary layer. The primary layer of material and the secondary layer of material also define a second sleeve passage substantially symmetrical to the first sleeve passage relative to the width of the primary layer of material.
