Claim 0:
1. A stretchable laminate comprising:
(a) a textile layer having a first surface and a second surface; and
(b) a fiber layer disposed on a first surface of the textile layer;
(i) wherein the fiber layer comprises a plurality of elastic fibers,
(ii) wherein the plurality of elastic fibers are disposed in a substantially parallel arrangement on the first surface of the textile layer, and
(iii) wherein at least 80% of the plurality of elastic fibers have an adjacent fiber spacing distance that is less than 2.5 times a thickness of the stretchable laminate in a stretched state;

wherein the stretchable laminate has an elasticity greater than an elasticity of the textile layer,
wherein the stretchable laminate has a recovery of at least 80% after an elongation of at least 10% in a direction of the elastic fibers, and
wherein the second surface of the textile layer has a maximum normalized surface roughness (Ra) of less than or equal to 25 micrometers.
