I thought 'stich has a suit where the Goretex wears out because it doesn't have an inner liner? The R3 Light?
It may be a 2.5 layer fabric. Similar to a 3-layer construction in which the membrane is bonded to an outer and inner layer, the inner layer on a 2.5 layer fabric is a much lighter material commonly consisting of a polyurethane (or something similar) that is coated on. This construction is of course lighter but is more prone to damage of that inner layer due to how thin it is and thus subsequent damage to the waterproof membrane can occur. In WL Gore's case, this fabric is marketed as Gore-tex Paclite.
