Baby Bjorn of the Steed

This leather harness was once a mere backpack with holes cut in it. It has since been transformed by the belief and deepest desire of its original bearer, When you wear the Baby Bjorn of the steed, you may carry one other humanoid creature in the bjorn.

While riding in the bjorn, the rider gains the following benefits:
The riders weight is reduced that of a large watermelon.
The riders size is reduced just enough that they can kick their legs about without touching the ground.
