Bottom Coating: Unlike many products in the market, we don't use PVC in our waterproof
protectors. PU (Polyurethane) is an incredibly convenient material for this job.
It prevents any liquid passing, it is breathable (skin friendly) and healthier (no
phthalates unlike PVC) . Completely washable.
Water Repellency: This finish provides extra protection in addition to PU coating.
We apply this finish on the top opposite side of PU.. Simply, this finish effects
the viscosity of the surface and liquids dance instead of passing into the textile.
