OMM Classic 25 | The Origin of Mountain Marathon Packs: Forging the Weapon of Lightness

OMM's classic model, evolving with the history of mountain marathons. A 25L backpack that combines lightness, stability, and expandability.

Run, climb, and keep moving forward. The OMM Classic 25 is a backpack that has continually refined the functions required in such active fields.

Its roots go back to 1973. Against the heavy canvas packs prevalent at the time, it was born from the philosophy that "lightness enhances functionality." This idea has been continuously passed down to the current Classic series.

Its easy-to-handle 25L capacity is suitable for a wide range of activities, from mountain marathons and fastpacking to day hikes, long trails, and lightly equipped mountain excursions. It's a superb size that can securely store necessary gear while maintaining high mobility.

It is also equipped with practical features such as EVA-padded shoulder harnesses for comfortable carrying, large mesh pockets for easy access to luggage, and UGR (Universal Gear Rail) for flexible expandability.

Furthermore, it comes standard with a Duomat back pad, which can also be used as a simple sleeping mat. Its design thoroughly considers not only lightness but also practicality in the field.

From races to mountaineering, long trails, and expeditions. This is a representative OMM model that caters to a wide range of activities with a single pack.
