What I bought was a large parachute fabric that had finished its original role. It is characterized by its light weight and strength. Although they look very similar, there are two types of fabric: ripstop fabric with threads woven in a grid pattern to prevent tearing, and non-rip fabric with plain weave. A number of products were developed by combining this fabric with handles made from reused dead stock and second-hand industrial belts.
I found the material in a certain town in India. In an area where military surplus items are distributed, I visited a small specialty store where used fabrics were piled up to the ceiling. The inside is so full of fabrics that it's hard to even call it a store, and there's no place to step. Guided by the man in the store, I climbed a huge pile of fabrics, pushed my way through the fabrics, and searched for things that were neither that nor that. I have an indescribable love for this material after hours of grappling with it like exploring a cave.
