Product Development STORY | KALCT HEATBLOCK

Forget the idea that long umbrellas are heavy and cumbersome. A 193g short-length design that changes your summer commute.
A new choice to make parasols more "free."
Opening and closing a folding umbrella every time you go out in the summer is surprisingly troublesome. However, traditional long umbrellas are heavy and a burden to carry around...
To resolve this dilemma, we poured the expertise we cultivated as a folding umbrella specialist manufacturer into a long umbrella. Our goal was a "lightweight long umbrella" you can grab without hesitation, even for a quick trip to the neighborhood.
The challenge of a unique "wind-resistant structure" and "short length"
Our biggest challenge was pursuing "lightness" and "compactness" while maintaining the convenience of a long umbrella.
We designed the total length to be a manageable "short length" and sought durability that wouldn't falter in strong summer winds. To achieve this, we adopted our patented, uniquely developed "integrated resin joint."
By arriving at a structure that flexibly deflects the impact of the wind, we achieved both lightness and toughness at a high level.
"193g of shade" created by aircraft-grade materials
We generously used aircraft-grade carbon fiber for the frame, achieving an astonishing weight of approximately 193g for the lightest color model.
The fabric features " HEATBLOCK," which not only provides 100% light shielding but also blocks near-infrared rays that cause skin temperatures to rise.
With a heat-shielding rate of up to 92.0%, it provides the feeling of cool shade even under the blazing sun. It also meets the demands of rain with a water resistance rating of over 13,000mm, making it a truly all-weather companion.
Under the summer sky, be lighter and smarter
KALCT HEATBLOCK is a partner that will make your summer more comfortable. Simply open it to block the sun, and carry it with ease.
We have condensed the portability of a folding umbrella and the peace of mind of a long umbrella into this one item. Our wish as developers is to provide you with the "freedom" to move without being at the mercy of intense heat or sudden rain.
