These diapers are the worst that I have ever tested. The fit is disastrous and they run after not even two hours of the day, even at night just before the hour. In addition, they slide down. 4+ is too short, 5 is much too loose. Very strange, I luckily found yet another brand diapers, a "cheap brand" that smells nor leaks, although the diaper if I Change servicekit morning, until the burst is complete.
Useless 2 stars because of the beautiful design and the reasonable price, unfortunately for me.
