Black Star bags was founded by Dave Stoops in 2006 in Portland, Oregon. It began with a free sewing machine and some used fabric. At the time Dave was a bike messenger and was in need of a waterproof backpack but could not find one with the desired pockets and features that a custom bag could provide. Nearly seven years and several hundred bags later, Black Star bags is producing some of the best handmade waterproof bags on the streets. -Black Star Bags
