Lightweight backpack for all occasions
Introducing the BUMMER backpack, one of TRAIL BUM's first models.

The fabric is made of durable and lightweight Spectra Ripstop fabric and is water repellent, making it safe even on rainy days. The outstanding storage capacity and user-friendly design make it an item that is useful in many situations from town use to leisure activities, not to mention on trails.






TRAIL BUM
We want to provide simple and lean gear and clothing. With this in mind, a new outdoor brand was born under the supervision of Highland Design, led by Tomoya Tsuchiya, a leading expert in ultralight hiking.








Lightweight and strong fabric
The 200 denier ripstop nylon fabric is made of Spectra, an ultra-high molecular weight polyethylene fiber. Even if the fabric should tear, it will prevent further progression. It has a water-repellent finish, so it can be used with confidence even in sudden rain.

In addition, the TPU coating on the back of the fabric increases the overall strength of the fabric, making it both hydrolysis and water resistant.

What is Spectrafiber?
It is said to be the strongest and lightest material on earth, developed by Honeywell, Inc. of the United States, and is used for sophisticated applications including bulletproof vests and helmets for the military, as well as armored vehicles and anti-blade gloves.






Excellent usability and storage capacity
The front has a large, easily accessible mesh pocket. It is useful for storing jackets and gear, and can be used in a variety of ways depending on the situation.



The main compartment can be opened and closed with an opening cord and a single strap.





On the side is a large gusseted mesh pocket with room for two 500ml bottles. The opening is designed at an angle for easy access while carrying the bag on your back. A cord is provided at the opening to safely store small items.






Comfortable to carry
The shoulder straps are inserted with padding that is both moderately soft and durable. The capacity and the weight that can be put into the backpack are calculated and finished in a perfect balance without excess or deficiency. Another key point is the thicker tape to prevent digging into the shoulders when the load becomes heavy.

The removable chest strap prevents the strap from slipping off the shoulder and allows for comfortable movement. The gray slider buckle is a whistle.



A removable back pad is placed inside. Not only does it support a comfortable backpack, but even those who are not confident about packing can use it with ease.






Comfortable and enjoyable on the move
The calculated capacity and design make this item ideal for a wide range of situations, including hiking and traveling, as well as town use.
