Japan Amvel KALCT Full Carbon Fiber Long Umbrella｜172g World's Lightest Long Umbrella · 8-rib Full Carbon Fiber Frame · 67cm Compact Long Umbrella · Easy-Dry Super Water Repellent · Wind Resistant 15m/s｜World's Lightest Carbon Fiber Long Umbrella

The KALCT is Amvel's new breakthrough—the world's lightest full-carbon fiber long umbrella, weighing only 172g. The umbrella frame is made entirely of carbon fiber, maintaining an ultra-lightweight design while still retaining a robust structure capable of withstanding strong winds and heavy rain. Coupled with the exclusive Easy-Dry water-repellent technology, it is a long umbrella that combines lightness with practicality.

✦ Why is this umbrella worth noting?

Long umbrellas generally have the impression of being "sturdy but bulky," and many people prefer to carry a folding umbrella rather than a long one. The KALCT breaks this stereotype—by using a full-carbon fiber frame, this long umbrella weighs only 172g, making it lighter than many folding umbrellas, yet it still retains the advantages of a long umbrella's wide coverage and smooth opening/closing.

✦ 172g, the world's lightest long umbrella

The weight of a typical long umbrella is generally above 300g, while the KALCT is only 172g, making it an extremely rare lightweight long umbrella on the market. Whether commuting with one hand or carrying it for extended periods, the burden of weight is significantly reduced, preventing hand fatigue during prolonged use.

✦ Full carbon fiber frame, combining lightness and strength

The KALCT's frame (58cm, 8 ribs) is made of full carbon fiber. Carbon fiber is known for its lightweight, high-strength, and high-elasticity properties, commonly used in aerospace and high-end sports equipment. When used in an umbrella frame, it significantly reduces weight while maintaining structural durability and wind resistance.

✦ 67cm compact long umbrella, easy to handle

The KALCT has an overall length of only 67cm, making it shorter and more compact than typical long umbrellas, classifying it as a "compact long umbrella" design. This length offers greater flexibility in handling, making it more convenient to open, close, store, and place than traditional long umbrellas, while still retaining the unique stable feel of a long umbrella.

✦ 15m/s wind resistance test, lightweight does not mean fragile

While the KALCT emphasizes extreme lightness, it does not sacrifice robustness. Official tests show that it can withstand wind speeds of up to 15m/s, making it highly reliable for daily urban commuting and general windy and rainy conditions. It is not a product that sacrifices durability purely for weight reduction.

✦ Easy-Dry water-repellent technology, lasting waterproof and more durable

The KALCT features Amvel's exclusive Easy-Dry water-repellent technology, which uses nano-particle water repellent treatment to cause raindrops to bead up and slide off the umbrella surface. Unlike ordinary water repellent treatments that can easily age and peel off due to washing or use, Easy-Dry's water-repellent effect has been proven by third-party tests to have stronger durability, maintaining excellent waterproof performance even after long-term use.

✦ Multiple colors available, UV cut rate varies by color

The KALCT is available in a variety of colors, with slightly different UV protection effects for each color. Darker shades (such as black and olive) generally offer better light-blocking and UV protection, allowing you to choose based on personal preference and sun protection needs.

✦ Product Specifications

UV Cut Rate (varies by color):

✦ Suitable for these people

• Those who want the stable feel of a long umbrella but don't want the weight burden.
• Commuters or outdoor workers who often need to carry an umbrella for extended periods.
• Those who value durable water repellency and don't want the umbrella fabric to lose its waterproof effect after some use.
• Those who want a long umbrella that is both lightweight and sturdy for use in windy and rainy weather.

✦ Usage Recommendations

• After closing the umbrella, it is recommended to shake off water droplets first, then stand it upright to air dry.
• In case of typhoons or extreme strong winds, it is still recommended to avoid using it.
• If the umbrella surface gets dirty after long-term use, wipe it gently with a soft cloth.
• While the full carbon fiber frame is sturdy, avoid excessive force or bending when testing it.

✦ Q&A

Q: Is the KALCT a long umbrella or a folding umbrella? What is the difference from the VERYKAL series?

A: The KALCT is a long umbrella and cannot be folded for storage; its total length is about 67cm. The VERYKAL, VERYKAL LARGE, VERYKAL 8, and Pentagon72 are all part of the folding umbrella series. If you are accustomed to using long umbrellas (e.g., for leaving at the office, in the car, or prefer the stable feel of a long umbrella), the KALCT's extreme lightness will be a significant upgrade. If you need to carry it in a bag, it is recommended to choose products from the folding umbrella series.

Q: At 172g, won't it break easily because it's so light?

A: The KALCT features a full carbon fiber frame. Carbon fiber itself has high strength and elasticity, and it has passed a 15m/s wind resistance test, proving its durability under normal use. Its lightness is achieved through material upgrades, not merely by thinning the structure, so there's no need to worry about the "lighter means more fragile" issue.
