"Even though it's a long umbrella, it weighs just 193g." Surprisingly light and highly heat-blocking, it makes summer outings comfortable.
KALCT HEATBLOCK eliminates the stress of heavy, bulky, and cumbersome summer umbrellas. Despite being a long umbrella with 58cm ribs and eight ribs, the lightest color weighs an astonishing 193g. This innovative parasol combines the convenience of a long umbrella with the agility of a folding umbrella.
[Three points of emphasis]
-
1. A full carbon frame that achieves an astonishing lightness of approximately 193g. The shaft, ribs, and support ribs are all made of lightweight carbon fiber, the same material used in aircraft construction. At about half the weight of a typical long umbrella (approximately 350-450g), it's easy to carry around all day without feeling like a burden.
-
2. Coolness like being in the shade of a tree "Heat-blocking effect rate of up to 92.0%" High-performance fabric blocks 99.9% of near-infrared rays, which are a heat source, preventing the temperature inside the umbrella from rising. With a high heat-blocking effect rate of up to 92.0%, it provides coolness like being in the shade of a tree even in the blazing sun.
-
3. The durable construction combines the reassurance of a long umbrella with the "flexible strength" to withstand wind speeds of 15 m/s. The resilient carbon fiber ribs and shock-absorbing "integrated resin joints" have been combined. It has passed the wind resistance test of 15 m/s, and is both lightweight and strong enough to withstand sudden winds and rain.
[Commitment to functionality and quality]
-
The fabric blocks out strong sunlight from multiple angles, with 100% shading and 100% UV protection (UPF50+), blocking out strong sunlight.It also blocks 100% of visible light, reducing the glare of midsummer and allowing you to go out in style.
-
Smart portability and ease of use: The overall length is 67cm, shorter than a typical long umbrella (approximately 84cm), making it slim and compact for portability. It remains convenient to open quickly with one hand, and won't get in the way when you're on the move.
"Long umbrellas are heavy and long" is a thing of the past. This short umbrella weighing just 193g will change your summer travel experience.
A new option to make parasols more "free"
When going out in the summer, opening and closing a folding umbrella every time can be surprisingly time-consuming. However, traditional long umbrellas are heavy and difficult to carry around... To solve this dilemma, we poured the technology we have cultivated as a manufacturer specializing in folding umbrellas into our long umbrellas. Our goal was to create a lightweight long umbrella that you can easily pick up even when going out for a quick stroll around the neighborhood.
The challenge of unique "wind-resistant structure" and "short length"
The biggest challenge was to pursue "lightness" and "compactness" while maintaining the convenience of a long umbrella. We designed it to be "short" in length for easy handling, and sought durability that would not be affected by strong summer winds. To achieve this, we adopted our own unique "integrated resin joint," which has been registered as a design. We arrived at a structure that flexibly deflects the impact of wind, achieving a high level of both lightness and strength.
"193g of shade" made from aircraft materials
The frame is generously made with aircraft-grade carbon fiber, resulting in an astonishing lightness of approximately 193g in the lightest color. The fabric features "HEATBLOCK," which not only provides 100% light blocking but also blocks near-infrared rays that can cause skin temperature to rise. Its heat blocking rate reaches up to 92.0%, providing coolness like shade even in the blazing sun. It's truly all-weather, with a water resistance rating of over 13,000mm, making it suitable for rain.
Under the summer sky, feel lighter and smarter
KALCT HEATBLOCK is your partner to make your summer more comfortable. Simply unfold it to block the sun and carry it lightly. It combines the portability of a folding umbrella with the security of a long umbrella. We want to give you the freedom to not be at the mercy of scorching heat or fickle rain. That is our wish as a developer.
Q: Why do umbrellas have different weights depending on the color? A: In order to maintain 100% light blocking even with light-colored fabrics, the PU coating layer on the back is adjusted to be thicker than with dark colors. This results in slight differences in fabric weight, resulting in differences in product weight. The lightest color is black, and the heaviest color is dusk blue.
Q: WHY IS IT SO LIGHT? ATo achieve both lightness and durability, the main parts, such as the center shaft, ribs, and support ribs, are made of carbon fiber, a high-performance material also used in aircraft and racing cars. Through a thorough review of the material and a unique structure, we have achieved a lightness that overturns the image of conventional long umbrellas.
Q: It says it blocks out 100% light, but does that mean it blocks out all light? AOur products have been tested based on JIS standards and have been proven to have 100% light blocking, and are of the same quality as products that are generally referred to as "complete light blocking." However, because there is a possibility that a small amount of light may leak through the seams of the fabric, we refrain from using the term "complete light blocking" to avoid any misunderstanding.

■ 撥水機能とメンテナンス
撥水加工は永久的なものではありません。ご使用中の摩擦、雨に含まれる不純物、皮脂等の付着により、徐々に効果が低下します。
撥水力が低下すると生地表面が濡れたように見えることがありますが、裏側に浸透していなければ雨漏りではありません。撥水力が弱まった場合は、市販の撥水スプレーでお手入れしていただくことで効果が回復します。
■ 開く前の準備
傘を開く際は、バンドを外して2〜3回軽く振り、生地と骨を十分にほぐしてから開いてください。生地や骨が絡まった状態で無理に開こうとすると、故障・骨折れの直接的な原因となります。
