Japanese labels doublet and POTR have introduced a collaborative bag that combines a mini backpack and a duffel, with two faces designed to be worn as the front. It is scheduled to go on sale October 10 through selected stores and online channels; pricing and quantities were not provided in the source report.
Japanese labels doublet and POTR have paired up on a bag designed with two equally usable faces, combining a mini backpack and a duffel in one silhouette. The collaboration is scheduled to go on sale October 10 through selected stores and online channels, giving shoppers a convertible design with different storage details on each side.
The concept borrows from the double A-side CD single of the CD era, in which neither track was designated as the secondary song. The bag applies that idea to its shape: rather than giving it a fixed front and back, the design makes either face an outward-facing option. One side uses POTR monogram jacquard and has a zippered front pocket sized for small items such as wireless earbuds or lip balm.
The reverse side takes its cues from a duffel bag, including a snap-button pocket. That pocket also has a practical role: its interior can hold the duffel handles when the backpack side is facing out, keeping those handles out of view. A turquoise lining, associated with POTR’s identity, runs through the interior. The report describes pink and khaki versions, with zipper tape dyed to match the body fabric.
The release includes an adjustable, detachable shoulder strap and a separate hand strap. The straps can be switched according to which side is worn outward, allowing the bag to be carried crossbody or by hand. The report lists availability at PORTER and POTR locations in Japan, a Hong Kong store, PORTER Korea and Bangkok, the Yoshida & Co. online store, and selected doublet retailers. It also lists separate stockists for collaborative apparel.
Two Bag Formats in One Design
The collaboration takes a familiar product category and changes how its sides are treated: the backpack and duffel are not separate modes hidden inside one bag, but distinct outward-facing designs. That makes the choice of which side to show part of how the bag is carried, while the two strap options add a second practical change in use.
For shoppers, the details to weigh are straightforward: two storage arrangements, two visible looks, and the need to switch the straps and tuck away the handles when changing sides. The design may appeal to people who want a bag that can shift between handheld and crossbody use. The available source does not establish how much it will cost, how many units will be made, or whether all listed retailers will carry every color.

A CD-Era Idea for PORTER
The source report attributes the concept to doublet’s design approach, which it describes as using humor and surprise to alter familiar clothing and objects. For this project, that idea is applied to a recognizable Yoshida & Co. bag format rather than to apparel alone. POTR is part of the Japanese bag company’s label offering, while doublet is the fashion label led by designer Masayuki Ino.
The double A-side reference supplies the design’s organizing principle: both faces receive their own construction and details, rather than one being treated as the main side and the other as an afterthought. The release information also identifies a separate apparel component to the collaboration, with its own store list. The report does not specify which garments will be offered.
“By not fixing the front and back and reversing the perspective, a new expression is born. The direction changes each time you carry it, and it resonates with your mood and outfit of the day.”
— Masayuki Ino, in a translated statement

Price and Stock Details Unreported
The source report gives a release date and a list of sales channels, but does not provide the bag’s price, production quantity, or whether availability will be limited. It names pink and khaki versions but does not say whether those are the only color options, or whether each retailer will receive both. The report also does not give product dimensions, capacity, or material specifications beyond the jacquard, lining, and zipper details.
