In addition to the Large that I listed in a previous posting, I also have an unused Medium (18-21in) Osprey Exos 58 in Basalt Black that I bought for my wife.  Asking $180 obo.  Pictures available here:

Similar to what happened to me with the Large, I bought this pack in two sizes for my wife, but in her case the Medium was too big and the Small was a fit. She only tried the Medium on in the home, and after a few minutes I put it back in the box and up on a shelf in my closet with the intention of sending it back soon.  But being the procrastinator that I am, by the time I got around to shipping it the return window had expired.  So I am hoping someone can use this.

Feel free to contact me if you have any questions or want more pics.  I can also send you my Ebay account name if you would like to check my reviews as a seller.  Thanks!
