TRAIL BUM / FAB 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.



Finished in a subdued color palette, the pack is also remarkably lightweight. Alongside its performance in active settings, it offers effortless everyday comfort that makes you almost forget the weight on your shoulders.





Designed to Adapt to Your Needs
With a 25-liter capacity, the pack is suited to day hikes, trekking, and fast hiking. The opening combines a simple drawstring closure with a single compression strap, allowing it to be adjusted according to the amount and volume of your belongings.



The front and side pockets feature breathable mesh construction, allowing you to see the contents at a glance. Drawcord closures help keep items secure, while the excellent ventilation makes them ideal not only for bottles and trail snacks, but also for quickly storing a shell jacket dampened by rain or perspiration.



The shoulder straps contain padding that balances gentle softness with lasting durability. Their thickness has been carefully calculated in relation to the pack’s capacity and intended load, creating a precisely balanced design without excess.

The chest strap can be attached at your preferred height, improving stability and creating a secure fit that remains steady during active movement. The gray slider buckle also features an integrated whistle, providing added peace of mind in emergency situations.



Loops are included for attaching an optional waist belt. This adaptable design allows the pack to be customized to suit different loads and your hiking style for the day.





The back pad is removable and can be used on its own as a resting mat. When camping, it can be swapped out for a sleeping pad inserted into the back panel, allowing for a minimalist setup that eliminates unnecessary weight.



The shorter back length makes the pack comfortable to carry even for users with shorter torsos. By keeping the load positioned close to the body and preventing it from sitting too low, it helps reduce strain while maintaining a surprisingly compact profile for its capacity.

Designed for both demanding outdoor activities and everyday use, its carefully balanced proportions sit neatly against the back, creating a clean and understated look.
