The surface layer is a faux cotton velvet surface layer, which instantly absorbs water within 10 seconds to keep your feet dry. The interlayer is memory foam rubber containing diatomaceous earth, which can effectively lock water absorption and quickly evaporate. The non-slip rubber bottom is closely combined with the ground to increase friction and adsorption, and it is not easy to move and has strong grip. Precautions for use: Due to the super water absorption effect of the bath mat, when the water absorption exceeds 2 times its own weight, please place it in the sun to dry
