In addition: the rucksack is quite heavy when I unpacked it I immediately thought, oh dear, and there are now all swimming gear to ....
Positives: The backpack is super processed, the zippers work smoothly, so have little rings so that they can be opened easily even with wet fingers, I like also the extra thick ring for hanging the backpack, convenient booklet are also the internal networks for shower gel, swimming goggles etc., but there are so many that they fill the interior of the backpack to unnecessary and paddles etc reinzutun but again too small.
Conclusion: for what I was looking for, the backpack is not ideal, too many small inside pockets, too small for swimming utensils like fins and Pullkick.
I think for the sport float without much equipment the backpack is good.
Processing speaks for the backpack
