This is a collaboration bag between Porter and Comme des Garçons, released last year. I purchased it at the flagship store in Yaesu Midtown. I've only used it 5 times, so I think it has very little wear and tear. The size is the largest, M size, and the color is the popular black. Please consider this opportunity. Color: Black Size: M Accessories: Dedicated storage bag, tags From the HP: This is a collaboration item between "COMME des GARCONS" and TANKER. To commemorate the 40th anniversary of the release of TANKER, Porter's representative series, We have produced a special collaboration item with COMME des GARCONS. Rei Kawakubo, the designer, designed and directed the TANKER helmet bag, which is available in three size variations. These three types of helmet bags are a size that has never been seen before in TANKER, and the color of the metal fittings and the fine details express the essence of COMME des GARCONS. On the orange nylon taffeta on the back, a graphic created for this collaboration was silk-screened. Each model comes with a pouch that fits in the front pocket. Orange nylon taffeta is used on the front, adding a design accent. The helmet bag (M) is large enough to hold B4 size documents. Although it has a thin gusset, the bottom gusset expands when you put things in it, and it has more storage capacity than it looks. In addition to the exterior front pocket, it has a removable pocket and two free pockets on the interior, allowing you to separate and store small items. Thank you for viewing.
