The 4elements roll-top backpack is designed and produced completely without the use of plastic. The backpack is largely made of Manila Fiber - a material combination of 76% cotton and 24% fibers of the Abacá plant, which also reacts water-repellent. All other individual parts, such as closures, buckles and zippers are made of metal. The backpacks are suitable for all who are looking for a gender-neutral, sustainable backpack as a daily companion for university, office or outdoor.
