This basic chemical business series is lightweight, has excellent water repellency, and is highly functional for daily use, making it suitable for a wide range of age groups. The main body fabric is 600 denier polyester oxford, and the back side is made of TPU-treated material. TPU (thermoplastic polyurethane) is lighter and more durable than PVC, and is also environmentally friendly, so it is a process that is widely used by outdoor brands. For the zipper, we focused on lightness and ease of use, and we used YKK Vislon's high-strength type called METALUXE Tough, which looks like a metal zipper. Glass fiber is kneaded into the resin of the Musi (element), making it 165% stronger than regular Vislon fasteners and 56% lighter than metal fasteners. The lining is made of 420 denier nylon oxford and has been treated with a Teflon fabric protector to increase its durability. Taking advantage of its property of not attracting dirt easily, the gray color is used to improve the visibility of the contents of the bag.
