Example apparatuses and methods are described for providing a swell packer apparatus having a vulcanized non-swelling outer layer with a pattern cut into it to expose an inner swellable sealing element. In an example embodiment, the swell packer includes a mandrel having a substantially cylindrical outer surface. A sealing element extends radially around the mandrel and a non-swelling layer circumferentially covers an outer surface of the sealing element. One or more grooves are cut in the non-swelling layer to expose a portion of the outer surface of the sealing element. The non-swelling layer is configured to prevent fluid communication between a swelling fluid disposed outside of the non-swelling layer and portions of the outer surface of the sealing element covered by the non-swelling layer.
