Super product !! Have I gained this drinking belt for long runs of our marathon training and did not regret it !! He sits super good, does not wobble and slip also nicht.Die bottles are sealed when they are not filled all the way to the edge ..... which is not always the case with the other bottle belt! Enough room for a bar, money , handkerchiefs and key .... all in all an asset to any ambitious runners !!! Would buy it again and again like to .....
