Abstract: A multi-layer bladder includes: a first bladder layer; a mask including a plurality of apertures; a second bladder layer bonded to the first bladder layer within the apertures in the mask and where the mask is not present between the first and second bladder layers, where the mask is configured to prevent bonding of the second bladder layer to the first bladder layer where the mask is present; and a fluid channel that is located between the first and second bladder layers and that extends to the mask from an outer edge of the multi-layer bladder.
