Multiple getest, the thing is waterproof :-) Very nice to wear - has namely good belts and the "bag" is very well finished in total. It is very nice that you can take out the back plate and can use it as a seat cushion. Very good are also the huge outside pockets - there is possible to neatly stash provisions :-) The idea with the inside pocket with zipper is good, the zipper certainly 10x tried everything goes wonderfully and it is very sturdy (large elements).
The material now acts not sooooo tough like other backpacks - that the backpack is very light
