Superficial Campers fascia which is a thicker fatty layer that can have a variable degree of thicknessFor example it is greatly increased in obese individuals and very thin in people with low body fat. Deep Scarpas fascia which is a thinner and denser membranous layer overlying the muscle layer of the abdominal wallIt is firmly attached to the linea alba and pubic.
