LC BY LOWERCASE
A luggage label by Yoshikage Kajiwara, representative of LOWERCASE, incorporating his extensive knowledge and experience of travel. Whether the journey is short or long, the importance of efficiently carrying what you need to enhance performance remains the same, from everyday commutes to overseas travel. The brand creates products designed to support every type of movement and journey.







Tough, without the bulk. The choice of 70D.
The main material is a water-repellent 70D polyester ripstop fabric.

Ripstop fabric is designed with a grid-like reinforcement structure woven into the material to help prevent tears from spreading. By using lightweight 70-denier fabric, this 30L bag maintains a lightweight feel despite its generous capacity, making it easy to carry for everyday use.

The surface has a smooth texture with a subtle sheen. Its refined appearance tones down the rugged look often associated with outdoor bags, allowing it to blend naturally into urban settings.

The water-repellent finish also makes it well suited to unexpected light rain. From daily commutes to travel, it is a practical choice for days when the weather is unpredictable.

※This product is not completely waterproof. During prolonged or heavy rain, water may enter through seams, zippers, or other openings.







Plenty of storage, without losing track of your essentials.
The capacity is approximately 30L.
The main compartment accommodates A4-sized items, making it easy to organize everything from work essentials to daily necessities while keeping the large capacity practical for everyday use.





The front pocket features dedicated compartments for mobile devices, cables, memo pads, and other small essentials. A key hook is also included, making it easy to keep your keys within reach and eliminating the hassle of searching for them at the bottom of your bag.





A dedicated laptop compartment is placed on the back, separate from the main storage area.

Because it can be accessed directly from the outside, you can quickly remove your laptop during commuting or at work without having to search through other belongings. It fits laptops up to approximately 15 inches, making it a reliable choice for commuting and business trips.

The zippers use YKK water-resistant zippers, helping reduce water intrusion and providing added protection for your laptop.



The left side features an open pocket for items such as a folding umbrella or drink bottle. The opposite side has a zippered pocket, ideal for storing small essentials or valuables you want to keep within easy reach.



As the capacity increases, stability and comfort become more important, especially when carrying the bag for extended periods.

To address this, a chest strap is included to help pull the bag closer to your body and keep it securely in place when carrying heavier loads.

The buckle features a magnetic closure for smooth attachment and release. When the chest strap is not needed, it can also be removed entirely.
