As far as waterproof materials go PU laminated fabric is pretty special.
It is a high tech product made by joining a layer of waterproof material to a sheet of fabric. The result is a soft material, which is completely waterproof. We don’t mean water-resistant. We are not talking shower-proof or any other description, which sounds a like it should not let water through. It is 100% waterproof, which means you can put the cosyplay mat onto wet grass and wipe it dry after use.
The PU surface is smooth, so no dirt gets trapped in it. And to make things even better, PU is anti-microbial, which means that no bacteria, fungi or house dust mites will be able to colonise on your mat.* This is not only very hygienic, but also avoids problems associated with asthma and eczema.
