TL;DR
Exoskeletons will not only make you run faster but will also increase your inventory size.What?
Exoskeletons main purpose is to enhance basic human abilities, including running but also including lifting heavy objects.As seen in this picture (I don't claim ownership) of a shipyard worker being assisted with an exoskeleton:
So then logically the exoskeleton should also increase the inventory size along with the armor upgrading the inventory by default.
