#89/ Flat backpack (light gray) / HD NYLON

If you would like gift wrapping, please purchase the [GIFT BOX M].

A sleek and slim design that highlights the refined suede-like texture of high-density nylon. Its simple yet elegant construction complements both casual and work styles, blending seamlessly into your daily life.

The silhouette is designed as a subtle trapezoid, slightly narrower at the top, to look the most balanced when worn on your back. This shape harmonizes beautifully with the warm texture of the fabric, giving the bag a soft and inviting appearance.

Designed with minimal embellishments for a clean, simple look, this backpack is also suitable for business use. It keeps your hands free, making it perfect for active days, whether you're commuting by bicycle or constantly on the move.

A kangaroo pocket is placed on the back, making it convenient for temporarily storing items like your wallet or IC card when carrying the bag in front. With no zipper, it's easy to access your belongings quickly and smoothly.

With its slim design, the bag fits neatly even in limited spaces such as on trains or buses, making it easy to use in crowded environments.

We also recommend styling the bag by carrying it by hand rather than over the shoulder. The handles are made from durable cowhide leather that resists stretching. The black leather adds a refined, sophisticated touch to your look.

Designed for everyday comfort, this bag features a compact width for a sleek silhouette. Weighing only around 340g, it's remarkably lightweight—yet still offers ample storage space to fit an A4 file, laptop, and even a tumbler with ease.

Since the Flat Backpack does not have built-in cushioning, we recommend using a protective case or cover when carrying items with sharp edges, such as laptops or books.

A fresh new material that captures the refined look of leather, yet allows for expressions that leather can’t achieve. While exploring alternatives to leather, REN discovered "High-Density Nylon" — a Japanese-developed fabric with exceptional character.

What surprises most people first is the feel and texture — so refined, it’s hard to believe it’s nylon. With a delicate nap and a soft, almost moisture-rich touch, it feels like it gently clings to the hand. Its elegant appearance is reminiscent of fine suede, offering a refined, luxurious look.

It is an ultra-high-density fabric with excellent water repellency, windproofing, and moisture permeability, and is widely used for clothing. Although the material was developed by a Japanese manufacturer, its high specifications are so high that it has been adopted as official equipment by the Italian military.
In addition to such functionality, what is noteworthy is that it has a touch and smoky look similar to suede or nubuck, and does not look like "cloth. It has a leather-like texture, yet can be expressed in ways that leather cannot. As such a rare fabric, we continue to use it with care and affection.
