Big kid pull ups

I cant remember the name of them, just that Imse Vimse made them. They are cotton but have a lining of PUL (waterproof) in them. They can be worn as underwear. I think they had sizes up to 65 lbs... but it has been a while since I looked. They are a Swedish company ( I think) and make cloth diapers too. Expensive, but when you figure in the cost of washing a few pair vs buying Goodnights ($10 to 14 a bag) they are cheaper in the long run. My son wore them, and loved them. I think they are called "Training Pants".
