Since reinpasst more than a 40 liter with carrying system. The stupid thing in the carrying system is but that it does not fit for small woman, no matter how great it would be, it is not useful and space is then not really there. The backpack has none, but the length fits, adjustable, woman gets stowed much and the backpack still does not depend so deeply that there is not cycling. So with the 12 beer what someone wrote here, skin down, I can imagine. I tried X backpacks. I still hope. And in the here I hope to have arrived. Burton delivers the quality and I have the perspective to be able to use this bag long and every day for everything. The division inside / outside that would make at least possible. Tested with different loads. I like the!
