Trail Bum BUMMER｜A Lightweight 30L Pack Inspired by the Roots of Ultralight Backpacking

A classic Trail Bum ultralight backpack, stripped back to only the features that truly matter.

Trail Bum BUMMER is a 30L backpack based on the brand's signature Steady model, further refined in pursuit of simplicity and lower weight.

Its design strongly reflects the philosophy of ultralight backpacks from the 1990s, while adding the comfort and practicality needed for modern hiking. By removing unnecessary features, Trail Bum has reduced the main body weight to an impressive 320g.

Despite its simple construction, BUMMER includes reliable features for real-world use, such as wide shoulder harnesses that distribute the load comfortably and large front and side mesh pockets for easy-access storage.

BUMMER does not feel like a backpack that simply removes features to reduce weight. Instead, it feels carefully considered, keeping only what is genuinely useful.

The wide shoulder straps are particularly impressive, distributing the load comfortably and pairing perfectly with a lightweight hiking setup. Even during long days on the trail, they help reduce pressure on the shoulders and allow you to focus naturally on walking.

The large mesh pockets are also highly practical for storing items you need while moving. BUMMER works well not only for hiking, but also for bicycle travel and everyday use. Its simplicity is exactly what makes it a Trail Bum classic you will want to keep using for years.

A Design Close to the Original Ultralight Backpack

With a main body weight of just 320g, BUMMER closely reflects the original ultralight backpacks developed in the 1990s. Its construction is remarkably simple: a main compartment with front and side mesh pockets, paired with shoulder straps. It serves as a reminder of a fundamental ultralight principle - a backpack can be made lighter through thoughtful simplicity, even without relying on highly specialized materials.

Wide Shoulder Straps for Balanced Load Distribution

Careful attention has been given to the width, thickness, and cushioning of the urethane foam shoulder straps. They distribute the load evenly across a broad area, while retaining their cushioning through extended use without feeling overly firm. Developed through numerous prototypes and discussions, these simple-looking straps play an essential role in maintaining a comfortable and balanced carry.

UV-Resistant Front Mesh Pocket

The mesh front pocket, a signature feature of ultralight backpacks, offers generous capacity for shelters, rain gear, and other equipment that may become wet. It uses soft mesh selected for its excellent resistance to UV degradation rather than maximum stretch.

Generous Side Pocket Capacity

The side pockets are also made from highly UV-resistant soft mesh. Although BUMMER has a relatively compact 30L main compartment, each side pocket provides enough room for two bottles. Their depth has also been carefully designed so that bottles remain secure while still being easy to reach without removing the pack, making them well suited to long-distance ultralight hiking.
