Herschel Supply Company Retreat 19.5L Backpack
Gray canvas-style shell (not sure but likely nylon / polyester) with red/white stirpe line
Brown leather strap / closure with magnic snaps
Small external pocket and adjustable shoulder straps
Main cavity closes with a drawstring
Padded laptop sleeve (guessing 16" compatible)
Small device pocket with wire passthrough for headphone cable

I carried this for about a year. It's in generaly good condition with a few small scratcehs on the shell (see front photo). Bottom is clean. Very solid and works well for a simple bag.
