Review on Stay Dry on Every Ride with the Domain Cycling Waterproof Bike Seat Rain Cover by Sam Carter

Bought for my daughter who rides her bike to school every day no matter what the weather. She used a grocery bag to cover her seat to keep it dry. I bought this as a treat (the grocery bag fitted great) so she could cover her seat in style. It rained heavily here, and today she tasted it for the first time. It didn't work at all. She took off the covers and sat down, and had to run inside before school to change her pants because her seat got wet. I looked at the cover after she left and it's completely wet inside. It *looks* like it should have worked, but it didn't. Not sure what's wrong with the design, the seams are sealed with some sort of tape as expected, but they seem to be leaking anyway, or maybe the material itself isn't fully waterproof. In any case, for us, for whom we bought it, it is useless.
