The backpack is made of two distinct outer and inner layer materials. This could well be the best of both worlds with the inner lining providing a waterproof interior and the external nylon fabric forming an impregnable outer covering. All the seams on the bag are done with double stitches, and this brings in a ruggedness not seen in the competing products.
