The main fabric of TYPE-A is polyester with a PVC coating on the back, which enhances the waterproofness of the fabric itself. TYPE-B uses CORDURA®︎500D nylon, which is stronger than regular nylon. The zipper uses YKK's VISLON WATER-R, which has a long-lasting water-repellent effect. There is a bias-cut card pocket on the front, and both types come with an adjustable strap, which expands the range of uses. TYPE-A comes in three colors, and TYPE-B comes in six colors, so the color range is wide.
