The fabric in this commercial backpack is made of home-produced fabric of wild giant nettle, spun and woven in a quite coarse quality of 7 x 5 th/cm. The inside is lined with a simple cotton fabric. The sack closes with a zipper, a sewn-on leather band. The front is fitted with a twisted cord, also of nettle is dyed with indigo. The string can be tightened to reduce the size of the bag.
