I purchased this swim diaper because so far this summer we spent a crazy amount of money on disposables. I don't find disposables extremely expensive but when you go through a pack a week the cost can get out of control. I figured that it was worth a shot to buy this because this swim diaper will cost me the same as a pack of disposables, why not give it a try. Well....i'm glad i did. We have had no problems with leaking and the diaper seems to do exactly what it says. My daughter is 27 months old with a very tiny waste and the 18-24 month is fitting her perfectly. I would recommend these to anyone looking for an alternative to spending a ton of money on disposables over an entire summer. Over the past few weeks it has paid for itself. Why not give it a try?
