We have 14 Grandchildren and one Great Grandchild. We use it for zip lining. It fits most of the smaller Grandchildren well and is easy to adjust. The problem is with the smallest ones. The harness does not adjust down far enough so we use carabiners to adjust down farther by pulling the torso straps in closer together.
