I am having a hard time with plastic pants / waterproof pants. I am a larger person and I am having a hard time finding good quality diapers that have the plastic backing. so i have found decent cloth backing diapers but i find that i have to wear plastic pants with them so they dont leak over time. My problem is i cant find plastic pants that fit right. as well as i find that the ones i am buying rip very easy on the sides after a few uses. can anyone make and suggestions as to a decent pair of plastic pants that don't cost an arm and a leg ( keep in mind i live in canada) or a decent diaper that is made in bigger sizes and has plastic backing (again not to expensive) as well as sizing for plastic pants. thanks for your input in advance.
