Dyneema's UHMWPE fabric is a material that is unlike anything out there. Put it on a pack and you've got a bag that's incredibly strong, lightweight, and resistant to chemicals. Cimoro is a new brand out of London, England with made-to-order bags that are constructed out of the paper-like material. The company is releasing three backpack styles that feature a patent-pending carrying system, 3M reflective detailing, and they even have one style that is so portable that it can be folded down to fit in your pocket.
