I bought two of these online for myself back in October in Medium and Large with the idea of trying them on and returning whatever did not fit.  I tried the Large on at home and found immediately that it was too big for my frame, so 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.  The Medium fit me quite well, and I find it to be an awesome pack.

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!
