Archival Clothing recently went out of business so there are probably only a few of these fabulous made in the U.S.A. roll top backpacks left! 

Dimensions: 18" H x 12" W x 5" D (rolled), expands to 24.5" H
Volume Capacity: 17.5 liters rolled and 23.5 liters unrolled
Weight: 2lbs 5oz

This sturdy canvas bag has a roll top closure with a  black Horween leather strap and brass buckle.  There is an interior stash bocket, two exterior side pockets that fit keys, a mini U-lock, a water bottle, etc.  The pack has a semi-rigid padded back panel and brass rings to adjust the shoulder straps, and a double-layer bottom.  Edges are bound in waxed cotton tape and all stress points are bar-tacked or riveted. A convenient Horween leather lash point on the front panel enables you to attach items like bike lights, etc. 

This item has been used to carry books/clothes/laptop, etc.  It is in very good condition.  There is one area where the stitching has come slightly undone due to my carrying heavy loads in the pack (see photo of stitching).  There is another photo that shows a bit of white that was on the bag when I first bought it (may have been some wax or chalk marking).  However, this isn't that visible as it is the part that is rolled.  Other than that, this bag is almost as good as new. 

I'm offering to send this in the large flat rate box. I'm happy to put it in a medium rate box which is a bit cheaper but then I will need to fold the bag more and squish it in!  But, if you prefer that please let me know. 

This item has only been in a non-smoking household.
