There are way too many factors as you can see from the responses here. It really depends on your wash routine, detergent, water conditions, laundry additives, child health issues, etc. I have never had any PUL go bad in six years of diapering. I have a mostly BG stash that is very used. Clearly, my experience has been much different from the several others that think BG has weak PUL. I believe this question has no concrete answer.
