The mechanical protection of the bag for the Navi is very good. The outer shell is stable, and the 5 "-Navi Garmin fits very well into it. The zipper works very well. The visible here elastic loops inside the bag are made of the cheapest rubber which have a very short useful life significant laxity. You look more like a baggy knickers rubber. Here would you prefer to take something better and more durable rubber and the unit prefer to make 1 euro more expensive. On the supplied large carabiner can hang another 5 kg of potatoes. Its dimensions are out of proportion to the content of bag. Then you just rips rather the belt loop of trousers as the hook. As Navis are affordable today, should such an alleged theft protection probably be exaggerated. The bag is only as good as its weakest component (the rubber).
