The main fabric is a lightweight nylon woven with 70d warp and 160d weft threads, laminated with a special microporous membrane (Breathec® by Toray Coatex Co., Ltd.) and then bonded with tricot nylon. This provides high water repellency, breathability (8,500g/24hr), and waterproofing (11,000mm water column).
The special microporous membrane in the middle layer has extremely fine pores measuring 1 to 30 micrometers, preventing water droplets while allowing vapor to escape. This material combines high water resistance with durability and lightweight design.

The leather accessories are made from chrome leather from MONFRTNI PELLAMI SRL, a long-established tannery in Milan, Italy, founded in 1898. After chrome tanning, the leather is finished with a semi-aniline finish, which combines vibrant pigments and transparent dyes and is applied on a roller coaster machine to create a vibrant and elegant color. This bag features a smooth, plain leather with a beautiful surface that exudes a subtle sheen. It's crafted from high-quality leather, unique to Monfrini Perami, a fashion-conscious European leather manufacturer.

5mm of high-expansion polyethylene foam is inserted into one shoulder strap to reduce strain on the shoulder, and the double-ring fastening, combined with a design that is consistent across the front and back, allows for comfortable use by either the dominant or left-handed user. The side pockets, adjustable with a cord stopper, are ideal for storing bottles and other items, and the snap hooks at the cord ends allow for keys, IC cards, and other items. Despite its

generous size, the bag's lightweight and soft three-layer nylon construction creates a sophisticated silhouette. This
casual series is perfect for everyday use, as well as outdoor activities and travel, thanks to its low bulk.
