Not waterproof , slip off of seat with normal use

So, these are most definitely NOT waterproof. Water resistant, yes, but if water gets rubbed into the material by you sitting on it, it'll soak through. These are also too small for my seat, (2014 toyota prius with optional bucket seats), when I sit down and scootch into the seat, the fabric eventually comes untucked from under the front of the seat. its still better than nothing though (assuming the heated seats don't eventually melt these).
