DELFY®, a waterproof and repellent fabric made from Toray's advanced technology, was adopted as the surface fabric. Nylon yarn with 70d aznd 280d tack, which is resistant to tension and friction, is used. The front surface is subjected to excellent water-repellent processing to repel rain, and the back surface is bonded with 0.2mm thick PVC to enhance its strength and waterproofness.

The interior fabric is made of BIOLINER®, an antimicrobial deodorizing material manufactured by Unitika Corporation. Ceramic antimicrobial agents are kneaded into the yarn at the yarn stage, and are resistant to friction and excellent in durability. In addition, deodorant processing (strong deodorizing effect) is applied to remove malodors such as ammonia and fish odors from the source by chemical reaction.

Pocket fabrics for laptops and smartphones are made of Doden®, an antistatic material that uses Belltron®, a conductive fiber. Electrostatic electricity generated by friction such as loading and unloading of baggage and drying in winter may charge the fabric and adversely affect electronic equipment. Doden® suppresses and removes static electricity by corona discharge.
