Our ballistic material has a DWR treatment on top and a waterproof PU backing applied to the inner surface (original ripstop material only; velvet ripstop does not have these features). These additions will help keep water from soaking into the bed, but seams can be a point of entry for fluid. For that reason, our covers are considered water-resistant, not 100% waterproof. Clean up spills as quickly as possible to reduce the chance of leakage into the bed, and avoid submerging the bed or allowing it to sit in puddled water.
Please note that water-resistance refers to regular water, as in moisture from weather, sprinklers, or water bowl spills. Bodily fluids like urine and vomit are more caustic and can seep past the DWR treatment and PU backing if not wiped up quickly. Frequent exposure to urine or vomit can damage these protective coatings, making the cover more vulnerable to fluids in the future.
