Jack Spade currently has a great sale going on and their Industrial Canvas bags are among the standouts.
Dipped Industrial Canvas is a 22 oz. tarp cloth canvas constructed with 3-ply cotton yarns and dipped in rubber latex for unmatched durability. All styles are unlined and feature custom Jack Spade rivets. Industrial canvas softens and fades over time and due to the porous nature of cotton canvas, will show signs of use, which adds to the overall character of the material.And don't forget to sign up for their promotional emails to get an additional 15% of your purchase.
