Product Description
Pargo Works Zen 25
■Excerpt from the manufacturer's description
Make your adventure easier
This modular backpack is designed for maximum comfort.
"For those who love to explore Japan's mountains"
・ZENN CONCEPT
"We stripped away the unnecessary and refined only the essential features." With this philosophy in mind, we completely redesigned the backpack. We aimed to create the ideal solution for today’s Japanese mountains—neither American nor European.
・ALL SEASON, LONG LASTING
We focused on a modular design that allows for expansion and a timeless, simple aesthetic so that you can carry it year-round and use it for as long as possible. It also features an excellent balance between lightweight construction and durability.
"The innovative ZENN SYSTEM adapts to your body"
FITS EVERY SITUATION
Designed to conform to the body at all times and reduce fatigue, the ZENN SYSTEM was developed through extensive research into backpack fit. We have also placed a strong emphasis on maintainability and expandability through its modular design.
・FLEXIBILITY
By positioning the shoulder harness attachment points lower than on a standard backpack, we’ve ensured effective shoulder length and flexibility, resulting in a superior fit. Even when the top stabilizer pulls the bag’s weight closer to your body, the fit remains unchanged.
・STABILITY
The wide shoulder straps distribute the bag’s weight across the entire ribcage, providing remarkable stability. This comfortable fit, inherited from the RUSH, reduces sway while walking and eases the strain on your shoulders.
・ADJUSTABLE HARNESS
A unique back design that integrates the back panel and shoulder straps. The Velcro adjustment system allows for a back length ranging from 38 to 48 cm, and thanks to the meticulously crafted shoulder straps, it fits both men and women equally well.
"A design that features only the features you really need"
・HIGH CENTER OF GRAVITY
Based on a slim silhouette similar to the Alpine backpack, this design optimizes weight distribution by adding volume around the shoulder blades. It features the high-center-of-gravity design inherited from the RUSH and BUDDY models.
・EASY OPENING
The tube-top-style opening can be opened and closed simply by pulling the drawstring, allowing for quick access even while wearing gloves.
・SIDE POCKET
The large side pockets are designed to hold two 500ml bottles. They allow you to access your bottles even while wearing the backpack and are constructed to prevent them from falling out unexpectedly. They are made from a highly abrasion-resistant stretch fabric.
・TOP POCKET
We positioned the top pocket in the most accessible spot when the backpack is on your back. It features a straight zipper for easy opening and is convenient for storing small items.
・HARNESS POCKETS
The shoulder harness features a pocket large enough to hold a smartphone or a 500ml water bottle. It offers the same user-friendly design as the RUSH and SNAP models. Starting with the 2026 models, an inner pocket has been added. Additionally, the zipper position has been improved for smoother opening and closing.
"Modular design for long-lasting play"
・ZENN SYSTEM
The harness and front pocket feature a modular design shared across the ZENN series. Whether you choose the ZENN RUNNING HARNESS for fast packing or the SNOW HARNESS for snowy mountains, you can select features tailored to your specific needs, making it versatile for a wide range of activities. Additional modules are scheduled for release in the future.
・FRONT POCKET
Combine the 5-liter front pocket with the harness to create a daypack. It’s perfect for summit attempts from mountain huts or for exploring after your descent.
・EASY MAINTENANCE
The sweat-stained harness can be removed and washed, so you can keep it clean at all times (please hand wash and air-dry in the shade; do not use a washing machine). In the unlikely event of damage, it is easy to repair or replace.
・LIGHT & TOUGH FABRIC
The main fabric features Extreema Grid Nylon, which utilizes ultra-high-molecular-weight polyethylene fibers. We selected this material for its lightness, durability, and timeless appeal. The bottom panel is made of ECOPAK, a fabric with high tear resistance.
"How to Try On"
・STEP 1
Adjust the back length using the 38–48 cm markings as a guide. Make sure the Velcro is securely fastened. Fasten the four clips to connect the harness to the main unit.
・STEP 2
Please fasten the chest strap with moderate tension. Pull the side straps to bring the vest snugly against your body.
・STEP 3
Finally, pull the top stabilizer strap tight to bring the load closer to your back. Use the hip belt as needed.
"High functionality with attention to every detail"
・SIDE BELT
The ZENN25 comes with eight loops and four side straps, making it convenient for attaching and securing gear. The lower side straps can also be fastened inside the pockets.
・KEY HOOK
There are two key hooks inside the backpack. You can also attach the MY FIRST AID or W-FACE POUCH.
・GEAR RING
Starting with the Spring 2026 models, we have added an O-ring to the bottom of the harness. This allows you to attach the SWITCH, FOCUS, and PATH FINDER.
・BACK PANEL
The back features a foam pad that can be removed. It can also be used as a simple mattress.
・HIP BELT
The hip belt can be attached or removed as needed.
