I bought this for biking to class in the rain (the bag is essentially waterproof) and just ever got around to using it (I have several messenger bags).

Condition: Very gently used - used it once in the rain and on a trip to beach (just a little sand). No cosmetic damage to speak of. Pocket organization is fantastic. Everything is in perfect working order

Retails for ~$100 on REI where I got it (http://www.rei.com/product/797679/timbuk2-classic-messenger-bag-medium).
Asking $60 cash (negotiable), on campus. I'm leaving Thursday so anytime before then is good.

Pictures show size relative to 32oz Nalgene. I can fit two giant Psych textbooks, a netbook, and a few notebooks with room to spare.
