- Brand: PORTER - Made in: Japan - Color: Black - Material: Nylon - Design: Simple design - Features: Metal fittings on the bottom This is the "PORTER STAGE" business series, which uses the original "Airtec1680" fabric, a plain-woven high-strength hollow yarn also used in military equipment. It offers a basic and extensive lineup to accommodate various business styles. Leather is used for the accessory parts, giving it a simple yet sophisticated look that is easy for adults to use. The main material is the original "Airtec1680" fabric, a plain weave of high-strength hollow yarn with excellent tensile and tear strength. It is a lightweight fabric, despite being a thick 1680 denier, thanks to the hollow structure of the yarn, which is 20% lighter than general nylon yarn. To achieve the functionality required of a business bag, such as being lightweight and self-supporting, a unique construction is used where the body, bottom, and top gusset are made from a single piece of fabric. Original hard nylon tape is used for the handles. By sewing this tape to the front and back of the bag, a structure is created that allows the bag to stand on its own without using core materials. In addition, by inserting piping along the sides of the zipper, the bag's shape is kept neat, and the zipper is easier to open and close. Please read the profile before purchasing.
