The Sanctuary MF Flat Mat has been lavishly topped with a layer of luxurious memory foam cubes that can easily be manipulated to make it thicker in the middle, evenly spread, or pushed to the outer edges to create a dished upper. Your catch can be placed on the outer layer of the unhooking mat, or it can be unzipped and used to create a cover. It comes with a large kneeling mat that also doubles as a handy storage pouch for your carp care equipment and scales.
