Skiphop Mini Backpack with Tether
My son has always been a runner. If I want him to go north, he bolts south. This was not working for our family, as we also have an older daughter who is in sports & school activities and we needed our son to come along(and sometimes actually walk) So I went in search of a tether backpack. Upon lots of recommendations, we found the skiphop bag. I was convinced it was our best choice with the tough to open chest clip. My son now refuses to go anywhere without his backpack. He loves putting his cars in it & takes it everywhere we go. We keep the tether strap in the side pocket so I can easily grab & attach if we need to.
