Mountains to the city
A multipurpose model with convenient back-side access

For those who walk far and long
ALK CONCEPT
ALK is a series designed around the concept of “in the mountains or in the city,” aiming to be just the right backpack. It features a comfortable carry and practical usability that let you walk anytime, anywhere, while remaining lightweight and durable.
ALK 30 FEATURE
The ALK30 features a unique back-panel access design, making it easy to access and organize your gear. Suitable not only for hiking but also versatile enough for travel and everyday use.
A design with excellent functionality and versatility
FITTING
It uses the same wide shoulder harness as the ZENN backpack. The load of the pack is distributed across the entire ribcage for greater stability. The ALK30 also includes an aluminum frame, providing solid support even when carrying heavier loads.
TOP STABILIZER
The top stabilizer pulls the upper part of the pack closer to your body, improving fit and optimizing load balance. This helps reduce fatigue during long hikes.
MAIN ACCESS
The main opening features a quick-access design that opens wide toward the body side. Tightening the inner drawcord creates a simple two-compartment structure, making it easier to organize your gear.
BACK ACCESS
The unique back-side opening design dramatically improves accessibility. A lightweight aluminum frame is built in to effectively distribute the load.
TOP POCKET
The top pocket features the large capacity inherited from BUDDY. It is ideal for storing items you want quick access to, such as snacks or gloves. The water-resistant zipper helps protect your gear from rain. A key hook is included inside.
FRONT POCKET
Ideal for storing rainwear or a wind shell. The zipper layout is designed so it does not interfere with the side belts or bungee cords.
SIDE POCKETS
The side pockets are sized to hold two 500 ml PET bottles. They are designed with a depth that makes them easy to access while preventing items from falling out. Once you get used to it, they can be operated while wearing the pack.
BACK POCKET
The inner back pocket includes a sleeve that can hold a hydration pack or a laptop. It is designed to meet the needs of everyday use as well.
HARNESS POCKETS
The shoulder harness includes a zip pocket that can hold a smartphone or a 500 ml PET bottle, allowing smooth access even while on the move.
FRONT INSIDE POCKET
The inner pocket on the front panel is ideal for storing items you want to keep on hand, such as rainwear.
MAIN FABRIC
The main fabric uses strong yet lightweight ROBIC 66 nylon with a polycarbonate coating on the surface. It resists water and dirt, making it easy to maintain.
BUNGEE CORD
The front bungee cord is convenient for temporarily securing items such as a wind shell. It can also be removed if not needed.
ATTACHMENT RINGS
There are rings at the lower ends of the harness for attaching a chest bag. SWITCH, PATHFINDER, and FOCUS can be used as front bags.
FITS WITH ZENN OPTIONS
The front panel is compatible with ZENN optional parts. You can attach accessories such as a snow belt or outer pocket.
DESIGNER'S VOICE
The name ALK comes from the Japanese word “aruku”—to walk. Walking is a fundamental human activity and the foundation of outdoor life. That will never change. Yet in today’s highly digital world, we humans have reached a point where we no longer need to move to go anywhere. “Walking = moving” has always been tied to curiosity about the outside world—perhaps that’s what we call the spirit of adventure. In times when information was scarce, people probably walked more and explored more.
Thinking about this led to a simple idea: let’s create a product that supports people’s desire to walk. A backpack that lets you walk anytime, anywhere. That thought ignited the designer’s spirit.
Surprisingly, the development process was smoother than ever before. After all, we had already built and tested countless prototypes through the development of RUSH and ZENN, and we had continued refining derivative models from BUDDY. Drawing on all that experience, development progressed quickly.
Of course, there were still challenges. The back-side opening of the ALK30, for example, took considerable effort. We repeatedly prototyped the frame and back panel to improve accessibility without compromising carrying comfort. Designing the front panel was another challenge. We wanted it to be compatible with ZENN optional parts while still having a distinct identity of its own. After much trial and error, we ended up with something that feels like a close relative of ZENN—and we’re quite happy with it.
There are many more stories behind its development, but as the tagline suggests, ALK is designed to work just as well in the mountains as it does in the city. A backpack that makes you want to walk anytime, anywhere.
So put on your ALK, follow your curiosity, and start walking.
Pack and go!
