I now see, that the liner on the bag you've got is similar to the UTG one, it's a little drawstring thing on the big inner pocket, right?
Now, I've got a technical question: the doo-hickey side pocket (like that technical term?) with the drawstring cord that goes through the top? What is that for, exactly? Water bottles? The cord seems like it might get annoying -- nevermind! I just went to test it out and noticed there's a velcro strap that'll let you strap/unstrap the bottle (or whatever it's really intended for!) from that pocket.
Way flippin' cool this bag... wonder if they make a flowered, paisley one?
