Gregory Nano Backpack Day Bag Listed as One Size (OS) Women's - presumable unisex - see pics for measurements. Very good, preloved condition. Pack has some minor wear and tear that you would expect with a used adventure pack. Has some minor smudges as I attempted to picture. Pack does not appear or feel too heavily used. Probably has very limited use based on feel. A nice higher end back with some nice features, compartments, and back/shoulder support. Has a compartment for a water bladder but the bladder is not included. Color might vary due to lighting.
