Marine Mat helm pad boat mats are unlike any other helm pads on the market. All boat mats are 12 mm thick and manufactured using a high quality EVA foam that we have specifically designed to be used in the marine environment. Installation couldn’t be easier, just peel back the backing and stick down anywhere on your boat! EVA foam is very stain and mildew resistant. Marine Mat products are backed by a 1 year warranty against defects in material. * Picture is for reference purposes only, actual product may differ based on your color options.
