nachfolger HY5 - packing the seat by using the included seatprotector

Quick as a flash our child car seat HY5 is packed in its bag, which is also the seat protector at the same time and ready to go for the next adventure. The total weight of the HY5 is less than 5 kg, it is 3x lighter and 5x more compact than conventional child seats. The HY5 rear-facing kids car seat provides continual safety for five long years. It combines the size groups 0/1 and uses its flexible form to give even larger children enough space to enjoy their travel time.
nachfolger - the next one is now

I would love to see a how-to of the travel kit, specifically the belt shortener
