Timbuk2 messenger bag with laptop sleeve

This bag has it all. Lots of pockets for your pens, pencils, calculators, you name it. Front zipper access will open from both sides. Two latching clasps that hold everything in. Nylon strap and extra cross body strap. Bottle holder (I did try this with my 40 oz hydro flask and it did not fit. But a Nalgene sized bottle will definitely fit. Used for a short time. Nice, durable fabric.
