We had ordered the ergolino of Ergobag and a backpack from Lässig for our five year old. Anticipation - we opted ultimately for ergolino. The Ayla has a very stiff material, works compared to ergolino cheap. The closure at the chest and the front of the pack lid is difficult for our little one to open, even for me as it is a flat pressure seal, where you have to press down a plate. The lap was a good catch, which is laterally compressed. At the back there is no protection against sweating, the ergolino here has a breathable back padding. The Erglino remains vacant on its own, the Ayla collapses because it has no solid ground and the back wall is not stable as in ergolino. The ergolino often appears to be a bit more difficult, but acceptable. The carriers make a good impression in two and both have a breast and a lap belt. The color combination is beautiful, in reality, the colors brighter and more intense than in the photo, the light green is not so pale, but truly a lush light green. We have given the many little things but opted for the ergolino, to our little had at first glance already prefer. For me it was particularly crucial that the ergolino remains empty and collapses and the material makes a higher quality impression. However it is also a lot more expensive.
