    Design history

    About design

    The second generation of the cache backpack has been planned for two years. From drafts, pattern making, shock test, and water repellency test, it has been modified and remade four times. After six months of actual experience, it has countless brainstorming. Feedback from the first generation of users, repeated revisions and tests, and finally launched our satisfactory work. The design highlights are as follows:

    • The design concept continues the brand's consistent "cache" principle, with the basic spirit of single shoulder carrying items that can be quickly taken out or stored, and the related detailed design of the pocket / function distribution, in order to allow users to quickly and easily take security or It is a storage item.
    • The main compartment (compartment B) with detachable three-way bending partition allows you to freely plan the most suitable vertical, T-shaped, up-down, or left-right storage space according to your needs.
    • The main compartment (compartment B) has a unique single mezzanine four zipper design, which allows you to quickly pick up items from both sides or the top of the backpack. You can open or close the backpack without readjusting the zipper.
    • The strap phone pocket / card pocket is a good helper when commuting, allowing you to free up your hands any time.
    • Special structure design (body structure / rigid foam material / sling down), whether empty or full load, the bag can be stiff and not collapse.

    ▲ Shock and load testing, single shoulder 8kg, double shoulder 10kg, drop height 25cm, 400 times passed.
     Rotate the zipper direction to open compartment B smoothly.

    We worked hard on the structure. The foam inside is made of hard material, and the structure point of the strap is moved down slightly. Whether you are empty or full, the bag is stiff and will not collapse.

    ▲ Whether empty or full, the bag can be stiff and not collapse. (Both backpacks have this same design)


    In terms of material selection, we continue the principle of "no animal fur" in the past, but we do not want the product to lose its durability and texture, and we do not want users to bear high costs in order to enjoy high-quality products.

    Outer material:Made of high-grade nylon fabric (dirty resistant / worm-resistant / mildew resistant / non-staining), the black models will dimly reveal gloss under the sun, low-key and rich texture.

    Inside material:Use 420D high tannin Polyester, high tensile strength, durable and not easy to break.

    Lower handle/straps:Made with 1000D high-tension webbing, good durability.

    Zipper sets:(YKK zippers),which is smooth and easy to pull. The interlayer A / B / C uses small pull tabs and drawstrings to make the backpack opening and closing more smooth.

    The outer packaging carton is made of recycled paper. We try to reduce the use of disposable packaging. There is no extra promotional materials in the packaging. The team hopes to provide quality products and contribute to the global environmental protection.

    We have compiled a comparison table of the functional differences between the two backpacks so that everyone can quickly understand the functional differences.
    In general, the Plus version is more: the mezzanine C can be fully opened and contains a laptop pocket / one more anti-theft zipper bag / can be placed horizontally on the luggage bar / the side has curved zipper bags and other functions The designs are the same, with only slight differences in size and weight.

    The general version is smaller in size, lighter in weight, and fully functional, and is suitable for daily commuting.
    The Plus version is slightly larger and has more pockets, suitable for professionals or when traveling.
