The material for this bag comes from at least 8-10 different pairs of post-consumer jeans, and post-industrial denim. The square-shaped boxes originate from our zero waste practices. This backpack contains 2 compartments and an inner separation for a laptop. The bag has an inner lining of ‘recycled felt’ material sourced from post-industrial scraps of the automobile industry. This felt layer minimizes the impact of water absorption by denim material during accidental spillage or light rains. Disclaimer: Every dwij Bag is unique! Thus, the bag delivered to you may have different shades of blue, however, the pattern remains the same.
