TRAIL BUM / Bummer Ultralight Hiking Backpack

TRAIL BUM
Driven by the desire to create simple, purpose-built gear and apparel, TRAIL BUM is an outdoor brand developed under the direction of Highland Design, led by Tomoyoshi Tsuchiya, a pioneer of ultralight hiking.







Exceptionally Light, Reliably Tough
The fabric is made from 100-denier ripstop nylon with excellent tear resistance. Its impressive durability stands up to abrasion and demanding use in rugged outdoor environments.



So lightweight that you’ll barely feel any strain on your shoulders, this pack keeps you comfortable and stress-free during active pursuits. The fabric is not overly thin, offering a dependable build that lets you carry your belongings with confidence.





Thoughtful Details That Adapt to Your Style
With a generous 30L capacity, this pack comfortably holds the essentials for an overnight trip. The opening features a simple drawstring closure and a single compression strap, allowing you to adjust the fit according to the amount and bulk of your load.



The front and side pockets feature mesh construction for easy visibility, with drawcords to help prevent contents from falling out. Made from durable, UV-resistant mesh, they are built to withstand frequent outdoor use and maintain their performance for years to come.

Thanks to the excellent breathability, the pockets are useful not only for carrying bottles and trail snacks, but also for quickly stowing a shell jacket wet from rain or sweat.



The shoulder straps have been meticulously designed with carefully considered width, thickness, and cushioning to distribute weight evenly across a broad surface. Durable polyurethane foam resists losing its shape over extended use, while providing a soft, body-conforming feel without being overly firm.

Though simple in appearance, the straps play an essential role in balancing the pack’s overall load and reducing strain on the shoulders.



The chest strap can be positioned wherever you prefer, enhancing the fit to your body and providing a secure feel that stays in place even during dynamic movement. The gray slider buckle also features an integrated whistle, offering added peace of mind in emergency situations.



Loops are included for attaching an optional waist belt. The high level of customization allows you to adjust the pack to your preferred setup based on your load and the style of each day’s hike.



The back pad is removable and can be used on its own as a sit pad during breaks. On overnight camping trips, it can be replaced with a sleeping pad inserted into the back panel, enabling a minimalist setup that eliminates unnecessary weight.





From Everyday Outings to Travel
Its thoughtfully designed capacity and exceptional lightness truly shine during hiking, mountain trips, and other active pursuits. With a minimalist look free of unnecessary elements and a sophisticated, understated color palette, this pack blends seamlessly into everyday outings and travel as well.
