Use a good piece now for several months (to sports, on the beach / sea) and it does, in spite of a reasonable price, even with everything. Einizg the externally mounted power for bottle transport is a little too small and dissolves slowly. the small additional pocket is really small. more than a medium sized purse is not pure. But who expected at the huge product transportation is wrong anyway. The comfort and practicality that is given thanks to the large zipper are clearly in the foreground.
