Casual backpack
Introducing a casual backpack that fits "simple, minimal, and ultra-light".

The fabric is made of durable and lightweight Spectra Ripstop fabric and is water repellent, so it is safe even on rainy days.

The simple yet well-calculated design makes it ideal for a wide range of activities, including leisure activities and hiking, as well as town use.






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. The water-repellent finish makes it safe to use even in sudden rain.

What is Spectrafiber?
It is said to be the strongest and lightest material on earth, developed by Honeywell in the U.S., and is used for advanced purposes including bulletproof vests and helmets for the military, as well as armored vehicles and anti-blade gloves.






Wasteful details
Simple construction with fewer sewing points. This has the advantage of reducing the number of broken parts, making it easier to repair.

A large, easily accessible mesh pocket is located on the front. It is useful for storing jackets and gear, and can be used in a variety of ways depending on the situation.



The main compartment has a roll-top closure. The storage capacity can be adjusted by extending the blowtorch according to the amount of luggage. In addition, a single strap placed in the center provides a sense of stability even when luggage is increased.








Comfortable to carry
Thin padding is inserted into the shoulder straps. The thickness of the padding is calculated based on capacity and the amount of weight that can be carried in the backpack, and is not excessive or insufficient. The straps are designed to be wide enough to distribute the load.

The removable chest strap prevents the bag from slipping off the shoulder and allows for comfortable movement.

The thin gusset width allows you to carry a small amount of luggage with less bias for a well-balanced carry.



The padding on the inside is removable. The bag can also be used as a sub-bag by removing the pad and rolling up the bag.






Modern Knapsack
The calculated capacity and design make this item suitable for a wide range of situations, including hiking and leisure activities as well as town use.
