It uses an original 3-layer structure fabric developed with the motif of the US Air Force flight jacket "MA-1". The 3-layer fabric of nylon twill (surface) + polyester cotton (middle layer) + nylon taffeta (back) is very light, and the soft feel of the bonding material and the vivid rescue orange on the back are attractive. This series is full of the thorough attention of Yoshida&Co. craftsmen in all processes from cutting to sewing and parts. This shoulder bag is recommended for a variety of occasions, from daily use to a secondary bag when traveling. Although it is compact, it is a two-layer type with plenty of storage space, and the front layer is equipped with partition pockets and clear pockets suitable for subdivision storage, making it convenient for storing items that are frequently taken out, such as smartphones and pass cases.
