This is a Porter sacoche. I purchased it around 2017, but haven't used it much in the last five years, so I'm putting it up for sale. I used it quite frequently for about three years after I bought it, so it shows some signs of wear, but it's still in good condition. The current retail price is 27,500 yen. The following is from the official website: [Product Details] Item No.: 737-17820 Brand / Series: PORTER HYBRID Size: W: 265mm / H: 180mm / D: 0mm Weight: 150g Material: Exterior: X-C1000 (X-PAC Cordura nylon) (some without X-PLY) Lining: Nylon ox (black hypalon coating) Attachment: Cowhide (combination tanning, water-repellent finish) [Product Description] This is a total series "PORTER HYBRID" that uses the original fabric "X-C1000" as the main material and offers a wide range of items from business bags to small accessories. It features an original fabric that is lighter and more functional than it looks, and has a calm design that suits any scene or style. The wide variety of items available is also attractive to a wide range of customers. "X-C1000" was developed in collaboration with "DIMENSION-POLYANT," which is known for developing sailcloth used in yachts and windsurfing, and "INVISTA," which produces many high-quality materials used in outdoor activities. It is an original fabric that combines "strength," "lightness," and "waterproofness." It is made of 1000-denier Cordura nylon, which is extremely strong and lightweight. On the back, X-PLY, which is made by twisting polyester into a string and arranging it diagonally (relative to the fabric), suppresses the diagonal stretching, which is a weakness of woven fabrics. Furthermore, by laminating (pressure bonding) a very thin PET film made of polyester using a patented manufacturing method, the weave of the fabric is sealed, preventing water such as rain and sweat from entering. This material combines strength, lightness, and waterproofness. The gusset uses fabric without X-PLY of X-C1000 to give the bag a beautiful shape. The handle attached to the front is made by sandwiching the tape with the same tape from both sides, which enhances the design and makes the handle stand firmly.
