H.C.PAX Round and Round Test
We just made a video of wearing the backpack while riding round and round on the scooter. We sped up the video and added music so it isn't so boring. We used the scooter so you can see the hands are always on the scooter and we rode around for a long time. At the end of the video we pulled out a bunch of books so you know there is stuff in the backpack.
