This Multipack now easier for him his work enormously and not only that: He drags it around everywhere with you! The part has exactly as much space as needed - not too much and not too little. Convenient for him is that the bag is in addition to fasten the leg and he is thus even be able to show off a lot of sports exercises without the bag slackens and he would therefore take it off.
The build quality is superb and the Multipack is recommended for all kinds of things (hiking, geocaching, etc.).
If the bag at any time buy back, if our times happen to lose ...
Edit: The bag is now more than a year in daily use - there is still no reason to complain! :)
