The S&S pad itself is definitely on the large side measuring Length 320mm Width 270 mm, but it's also incredibly thin. It measures just 2mm tall. One of the first things you'll notice when picking it up is the rather odd feeling pad backing. It is not rubber feet or foam rubber but rather a motley applied rubber type finish that reminds me of the spray on Rhino truck bed liners. It looks almost splatter painted but once you feel it, the sticking effectiveness is easily understood.
