Chrome Industries has probably saved many a bike commuter by providing durable bags that can carry a lot, but the company is truly the rescue with its line of durable BLCKCHRM bags. These are made form hypalon, material originally used to make U.S. Coast Guard rescue rafts. These bags feature liners with tightly woven nylon, while the trim is full grain leather and hardware is coated with rubber.
These American made bags are guaranteed for life.
