TRAIL BUM
Designed with simplicity and functionality in mind, TRAIL BUM was created under the supervision of ultralight hiking pioneer Tomoya Tsuchiya and his team at Highland Design. The brand focuses on crafting outdoor gear and apparel that embrace the essence of minimalism and efficiency.







Lightweight yet durable fabric
Made from "Ultra 200X," a cutting-edge fabric developed by U.S.-based Challenge Sailcloth. This high-performance material is designed for superior water resistance, abrasion resistance, and impact resistance, making it a reliable choice for extreme environments.



A waterproof film lining adds extra protection, keeping your gear safe even in unexpected downpours.

The seams are reinforced with piped edges to enhance durability while eliminating seam tape, preventing deterioration and peeling over time.

*Note: This product is not fully waterproof.





Versatile storage and adaptability
The main compartment features a roll-top closure secured with snap buttons for added convenience.





The roll-top extension allows the storage capacity to be adjusted from 13L to 19L, adapting to your needs.





A front mesh pocket offers additional storage space, large enough to accommodate bulkier items such as a helmet. The bottom of this pocket is reinforced with Ultra fabric, ensuring it can securely hold items like a snow shovel blade without damage.



Comfortable carry
The shoulder straps are constructed from durable "Spectra" fabric with soft padding, ensuring comfort even when carrying heavier loads. The addition of wide straps minimizes pressure on the shoulders for a more secure and ergonomic fit.

A removable chest strap prevents shifting during movement and improves weight distribution. The gray slider buckle doubles as a whistle for added safety in outdoor environments.



The interior features a detachable back pad, offering extra support and stability while making packing more user-friendly.





A modern take on the classic knapsack
Thoughtfully designed with optimal capacity and a sleek silhouette, this bag is perfect for both urban use and outdoor adventures, from hiking to leisure trips.
