lululemon pure gym bag
Totally doesn't look like a gym bag. There are laptop and cell phone compartments and a dry pack for wet clothes. Great for taking as a carry-on when flying. The straps are only long enough to hold as a hand bag, but comes with a detachable shoulder strap for when you're carrying a lot of stuff.
I like this lulu bag for the gym and/or travel. Not sure how much it costs.
