Features of the Square Backpack
#1 Simple and high-grade. A special backpack for adults who want to wear high quality.

While retaining HushTug's signature "ultimate simplicity," we have created a square-shaped backpack with gentle curves that give it a high-grade impression.
#2 Luxurious use of Himeji leather, highly regarded around the world
We use luxurious cowhide produced by a tanner (Nakajima Leather Industry) in Himeji, a city famous for its leather.
Enjoy the strength, suppleness, and beautiful changes that occur over time in Himeji leather, which is made using traditional techniques cultivated over more than 65 years of history.

#3 The attention to detail that went into the square backpack
1. A square shape with gentle curves. The shape exudes a sense of luxury and complements business attire.

2. There is no compromise on storage capacity. You can use this bag for your everyday work, or for a business trip for 1-2 nights.

3. The backpack has a zipper all the way to the bottom and opens wide. It is designed to make it easy to take out items from the bottom even when it is full.

4. The back is made of mesh. It fits your back well, so you won't get tired even if you walk for a long time, and it is breathable even in hot weather.

5. There are two zipper pockets on each side that can be used while wearing the bag. They are in close contact with your back, so security is also assured.


6. Square-shaped backpacks tend to become dented at the top when heavy items are placed inside, but we have designed this backpack with a hard core material at the top to keep it in good shape like new.

Square backpack before minor change

7. The simple design without any unnecessary elements makes it suitable for use with a variety of outfits.

8. The adjustment parts are finished in chic black metal fittings and can be adjusted in four stages.

9. The inside is made of suede-like fabric, giving it an elegant and smooth texture.

10. It has a cushioned PC pocket to protect your valuable PC from external shocks.

11. There is also an inner pocket below the PC pocket. Small items such as a long wallet can be securely stored.

12. In pursuit of ultimate simplicity, the logo is only printed on the inside. When you take something out, please remember HushTug.

13. The zipper is YKK EVERBRIGHT (size 5). Not only is it stylish, but it also opens and closes smoothly.

14. The leather is chrome tanned, which makes it resistant to scratches, water stains, and color fading, and allows you to use it for a long time in a beautiful condition.

Below, we examine how resistant the Himeji leather used by HushTug is to scratches, water stains, and wrinkles.

#5 Product sales
This square backpack was made by a Japanese sewing company with cutting-edge technology, in collaboration with Himeji leather, which is highly regarded around the world.
Despite Japan's garment factories having a long track record of production, including for high-end brands, and having solid world-class skills, they are suffering from a chronic lack of successors and the impact of the COVID-19 pandemic.
Therefore, we decided to jointly develop a product that combines HushTug's simple design with Himeji leather, which is highly regarded around the world, and Japan's excellent sewing techniques.
This project was launched to pass on the world's finest Himeji leather and sewing techniques to future generations.
The product that carries that hope is a product that HushTug is proud of.
Please look forward to it.
