I really like the Adv Spec guys and usually find their stuff suits my tastes/needs. This seems a bit expensive for what it is though; for that money, you could get a Giant Loop Great Basin or a Kriega Overlander 30 (and a US-10 to go over the top to boost it to 40 litres) and have (a not inconsiderable pile of) change. Both of those products are real "cream of the crop" ones. I'd be really interested to hear: What does this offer over those that lead the OP to choose to spend their cash on these instead? Not criticising your choice, just interested.
