BUDDY school bag with growth function

Correct size and adjustment for the finkid BUDDY school bag: The correct adjustment of the finkid Buddy school bag depends less on the child's height than on the child's back length. Therefore, it's worth trying out the different sizes individually.

A good reference point is the position of the hip fins: They should sit centrally on the hipbone—not too high on the waist and not too low on the buttocks. If the fins sit too high or too low, the back length can be adjusted accordingly.

Tip: Try out several settings and see which one makes the backpack sit ergonomically and is comfortable to wear.

Which hip belt fits? With the BUDDY CLASSIC, the straight hip belt is generally suitable for children up to about 130 cm tall. However, individual stature is crucial. If the belt no longer sits comfortably on your hips at the largest back adjustment, we recommend switching to the hip belt with curved fins.

Important when attaching the hip belt:
The wide parts of the belt (the fins) should point downwards when worn – this is the only way they rest correctly on the pelvis and ensure optimal weight distribution.
