Duffel bag with two side storage pockets The interior of the main unit is also equipped with a zip pocket. Comes with a shoulder strap, so it can be hung from the shoulder. The fabric is made of 500D (denier) Cordura nylon. Nylon is a fabric that has excellent tear strength and abrasion resistance, and is softer to the touch than polyester. In addition, the nylon itself is water repellent, and the back side has a polyurethane coating that is not completely impossible to prevent water from entering. The storage is not only made of Cordura nylon, but also has a 210D polyester lining to prevent the lining of the fabric from being seen, so it is not only comfortable to the touch, but also can be used even if the PU coating is degraded. The zipper is made from a special YKK material that has received a high reputation from around the world, so it is easy to open and close.
