Gravis Battery Backpack

Purchased this pack off Whiskeymilitia.com for only ~$19 which is a great deal for any laptop pack. I purchased the military color and it looks nice, the other reviews are correct in saying, "a nice profile". There's plenty of space on the inside and enough compartments for all kinds of stuff. I especially like the fleece lined zipper pocket in the main compartment; it can fit much more than just a cell phone so it makes a nice stash pocket for valuables. My 17-inch HP laptop fits nicely in the compartment even with the extra inch on the bottom of my laptop from the 12-cell battery. My only issue is there isn't much of a place to store pens and pencils; the pack does have interior pockets for this purpose but they're way too deep so I find myself digging around in there to grab what I need. Also, I'd advise whoever purchases this to take it easy on the zippers, some of them don't feel very sturdy but I haven't had any problems yet. Certainly a nice upgrade from an ugly, clumsy Targus laptop backpack I first used when I got to college. The only thing I liked about the Targus more is it had two insulated beverage pockets (Gravis has two smaller, uninsulated ones) and one insulated compartment that could fit an entire lunch; all these extra features would probably explain why the Targus is twice as big and ugly than my new Gravis. Oh, I should also mention your laptop will likey be in pieces if you take a spill while riding a skateboard or bike. In fact, there really isn't any padding at all so I wouldn't recommmend this for those who plan on eating sh*t on their way to class while wearing this pack.

This bag is easy on they eyes, but has tons of space. The main pocket has a lot of little pockets in it for storing electronics/smaller items, as well as a lined/insulated pocket for a phone. The laptop compartment is giant, and seems to be pretty well padded. The pockets on the sides for waterbottles have elastic in them, but no drawstrings to adjust with. This bag is perfect for around town or in and out of class.

This bag is perfect for everyday life, Laptop pocket fits the macs. Wicking mesh straps and insane colors. The Blue has a bike crank on it, geared towards the fixie culture (no pun intended).
Lower profile for the caliber, like a LCP ruger (google it!)
