End the binary choice between long umbrellas and folding umbrellas. A new option brought to you by the ultralight long umbrella.

"A 30% chance of rain today... should I take my folding umbrella, or the more reliable long umbrella?" Have you ever spent your rainy mornings agonizing over such a small decision?

Until now, we've had to choose between the portability of a folding umbrella or the better coverage of a long umbrella. However, the KALCT, a long umbrella developed by Amvel Co., Ltd., brilliantly redefines that boundary.

About half the weight of a plastic umbrella: The shock of starting at just 172g, surpassing folding umbrellas

The most striking feature of the KALCT is its surprising lightness the moment you hold it.

Despite having 58cm ribs—a size that easily covers the shoulders even for an adult man—it weighs as little as 172g in its lightest color. This is less than half the weight of a standard convenience store plastic umbrella and lighter than many high-performance folding umbrellas.

Because it weighs about the same as a smartphone, it significantly reduces the stress of carrying a long umbrella, which is usually considered heavy and cumbersome. This lightness has evolved the long umbrella from a "tool for special occasions" into a "daily companion you can always rely on."

Technology that combines the "reliability of a long umbrella" with "portable lightness"

How was such weight reduction possible? The secret lies in using carbon fiber, a material also used in aircraft, for the frame.

It achieves a high level of both lightness and strength, and is designed to be compact with a total length of approximately 67cm, making it easy to maneuver through crowds and on trains. It opens and closes quickly, and bundling the wet fabric is simple. It maintains all the inherent conveniences of a long umbrella, but with the ease of carrying a folding one.

A smart new choice that eliminates "compromise" on rainy days

"I’m not sure if it will rain, but if it does, I want to stay properly dry." The true value of the KALCT shines on days with such uncertain skies.

By eliminating the option of "not taking one because it's too heavy," you can always be prepared with the best gear. This removes the need to buy disposable plastic umbrellas during sudden rain showers, leading to a lifestyle that is economical, eco-friendly, and, above all, aligned with your own aesthetic sensibilities.

Why not spend your rainy days more freely and smartly with the KALCT, an umbrella that redefines common sense?
