This basic chemical business series is lightweight, highly water-repellent, and offers enhanced functionality for daily use, making it suitable for a wide range of age groups. The main fabric is 600 denier polyester oxford with a TPU coating on the back. TPU (thermoplastic polyurethane) is lighter and more durable than PVC, and is also environmentally friendly, making it a very popular coating among outdoor brands. For the zipper, we adopted a high-strength YKK Vislon type called METALUXE Tough, which prioritizes lightness and ease of operation while looking like a metal zipper. By incorporating glass fiber into the resin of the elements, it achieves 165% higher strength than a regular Vislon zipper and 56% lighter weight than a metal zipper. The lining is made of 420-denier nylon oxford with a Teflon fabric protector coating for enhanced durability. Taking advantage of its stain-resistant properties, a gray color is used to improve visibility of the contents of the bag.
