Both models are ergonomic and have enough space for everything you need at school. The prime set backpack has 2 more velcro surfaces for Kletties and zippers for Zip-Sets. The prime set is therefore more customizable than the prime. In addition, the set contains a Pencil Case, a Folder Box and 4 Kletties in addition to the ergonomic backpack.

Yes, this is very important. Books and other items often make primary school children's backpacks quite heavy. In order to optimally distribute the weight and prevent fatigue, an ergonomic school bag must not only have a padded back and shoulder straps, but also be well adapted to the child's back with chest and lumbar straps. This allows the weight to be transferred evenly to the stable pelvis.
