The North Face backpack, Martin Wing, model NM61526. I believe the size is 6L. It's blue. I bought it used 4 years ago for running, but since it's 6L, I couldn't fit much in it, so I used it about 10 times and then it's been in the closet ever since. As far as I can tell, there's no damage to the zippers, so I think it should still be fine to use. The logo is still there. *The 6th photo is for reference. *Please consider purchasing, understanding that it is a used item. *I plan to ship as quickly as possible, but it may be on the weekend due to work. Thank you for your understanding.
