After having my stuff stolen on vacation, I became obsessed with creating the toughest most theft-resistant bags the world had ever seen. In two years we went from idea, to Kickstarter, to getting a sport on ABC's Shark, which catapulted our growth even further. With a loyal following of backers, customers, and brand ambassadors, we have become globally known for creating the toughest bags in the world. - Don Halpern Founder/CEO
