I would highly recommend this product for someone who jogs much. The Halterrung sitting really close to the body and not slackens. I use it now about half a year and can still detect any wear or deterioration in wearing comfort. The belt also a not hindered. It is important that you fill the bottle only to the limit mark, otherwise it will overflow. In addition, I also suppose sometimes with only 2 Flschen and have not felt that they sit unevenly on the body. Points are deducted there from me, because a bottle is leaking. Otherwise strong buy recommendation.
