This is a neat little bag, and I do mean "little".
This bag would work best for a minimalist person, its not intended to carry a lot of things. So if your looking for something to carry your laptop in, this is not the bag for you.

It works perfectly for what I need it to do. The bag fits my 10" tablet, a Molenskine journal, & a couple of sync cables.  If I add my headphones (over the ear not ear-buds), its starts to get bulky (so I'll look for fold-able headphones to minimize the bulk). In the front pockets (which are closed via Velcro) I have a couple of flash drives.

The over the shoulder strap is of course adjustable to make it as long/short as you like. The front flap lock takes getting used to, but once you do it a few times it will make sense. I actually like it better then a normal Velcro, its more secure in my opinion, and I think is part of its charm.

I had gotten the military green one for about ($10) here on amazon, and I have to say I'm very happy with my purchase, it fits the minimal objects I like to carry with me, its very light and sturdy, and arrived VERY quickly.

If your a minimalist, and want to just take your tablet (11" or smaller) and some quick small stuff with you on the go, then this is a good bag for you.

I hope this helps :)
