Caveat: I am not by any stretch a bag guy. Sucker for canvas though and especially the browny ones that sort of remind me of the old LLBean duffle bags.
Details via the owner/designer Noah Guy; Joshu+Vela designs and hand-makes totes, backpacks and wallets in San Francisco using USA grown and woven organic canvas (4 Martexin waxed canvas colors and indigo dyed), leathers, brass hardware and natural dyes. The bags are available at Union Made and The General Store in San Francisco, $200-$300 range.
