We had for the first child already Imse Vimse training pants. Although these were 100% leak-proof, but very thick and still looked after from diaper, so I wanted something different for the second child, which more looks like underpants and especially is not as outrageously expensive as Imse Vimse & Co. These training pants are super here accepted by the child, are easy to take off and not look absolutely for diaper. Waterproof 100% I would not say, but they catch smaller margins on fine, so that the child is not the same as in a puddle when it has not enough time. Our child was with these pants after ten days dry, is now completely independently to the bathroom, a huge success, so just buy it. Plus for this unbeatable price, I give five stars, although at a four pants at a seam hangs a thread. 90cm corresponds incidentally size 92nd The pants come from China and are shipped from Hong Kong, so the delivery takes a little longer, but worth the wait.
