Is this pack last year's model? And if so are there really any befits to buying the newer one? Thanks!
I got this pack and it works fine I think you should be good. its a killer deal
No clue. Despite that, I'd say your answer depends on what kind of price differential there is between what you see on this site and what you can find elsewhere. I can't imagine that any new features will be leaps and bounds above what this bag (which I have been using for a few months now) offers, especially if this price is a good amount lower than others you've found.
This site had the best price I could find for this bag by far.
Sorry for the non-answer, good luck.
