I just received an AIO Leakmaster from adultclothdiaper.com yesterday and am extremely frustrated with the performance. I was under the impression you didn't need to even wear plastic pants but I did so anways just to be in the safe side. It leaks, horribly. I feel the sizing is correct. It fits very snugly. I am just surprised at the diapers minimal absorbancy. I didn't add any inserts so maybe that will help a little, but for a $50 dollar cloth diaper plus $15 in additional shipping charges (that cost a mere 7 bucks) I feel ripped off. I've been using disposables for some time and this was my first venture into the cloth market so I may just be doing something erong. Adultclothdiaper seemed like a good company so any help is greatly appreciated.
