Already during the first use of this belt, I was very impressed. The belt fits perfectly and does not wobble around (I chose size M - when Jean width of 31 "). He holds the bottle thanks to the plastic bracket reliably, while they are still easy to take out and insert again.
In addition, provide the bottles with a total of 840 ml of a relatively large volume of liquid - the product is therefore suitable for longer runs. And for ultra runners like me
The belt is in any case other copies, which have only rubber mounts for bottles, preferable - especially as it does not cost much more than this.
