For packing the goods I wanted to put not even two points, but a stake. Just a stake. Since in such a package the goods could be damaged very easily. And the bag should be waterproof) but when I checked the goods I was surprised by the very good workmanship. With density in 600D (tactile I would confirm it) the bag is light. Seams and fasteners of belts and accessories are very high quality. The color is just a bomb! I bet of course five points) but, my friends, ahead of the so-called vaning... (trial and torment with water in the bathroom). Given that the bag should serve me in the sea-ocean and mistakes there are not farewell-the test will be worthy, then I will write my second review. Let's see if this bag and its store endure.
