I was slightly surprised to see that this pack is not set up for carrying a hydration system. I mean, that's one of the signature design features of a BLACKHAWK! pack, right? Instead, obviously with the market in mind, this pack has a small port incorporated that would allow you to run headphones or other small wired devices, from inside the pack to outside up near the carry handle. Such allows you to carry your iPod or other electronics inside the pack in that top interior pouch and run the wire out so you can listen to your tunes.
All in all the pack served me very well at SHOT Show. At home I can see it serving well in the role of a book bag, relaxed office "briefcase" or laptop bag, or as a general carry all. MSRP is just under $110 but I'm sure you can find a better price on it if you search the web a bit. For more details and specs about it check out BLACKHAWK! online.
