Freedom from "light but hot" or "cool but heavy."

With the extreme heat in recent years, the performance we seek from parasols has been increasing year by year. In particular, the combination of "heat insulation" and "lightweight" is a sincere wish for many users. However, these two elements have long been in a trade-off relationship.

Generally, to improve heat insulation, the fabric must be thicker. On the other hand, if you pursue weight reduction, the frame must inevitably be delicate.

Attempting to support "heavy fabric" with a "light frame" causes the fabric to sag or the overall balance of the umbrella to collapse, resulting in an uncomfortable user experience.

What AMVEL aimed to do was resolve this physical dilemma.


0.06mm heat shielding technology, thinner than paper

The solution to this difficult challenge is AMVEL's proprietary material, "HEATBLOCK." We overturned the stereotype that "heat-insulating fabric must be thick and heavy" and pursued extreme thinness.

Its thickness is a mere 0.06 to 0.09mm. This is even thinner than standard copy paper.

Because of this overwhelming thinness, the fabric fits neatly even when combined with a lightweight carbon fiber frame, creating a beautiful sense of unity throughout the umbrella.

It features a beautiful silhouette when opened, suppresses flapping when caught in the wind, and provides a stress-free user experience. Naturally, the thin fabric is also extremely compact when stored.

It doesn't take up space in your bag, becoming "coolness" that you can always carry with you.


No compromise on specs. Highest level of shielding performance

There is no need to worry that "if the fabric gets thinner, the performance will drop." While pursuing extreme thinness, HEATBLOCK maintains the highest level of specifications for a parasol.

  • 100% Light Blocking Rate

  • 100% UV Cut Rate

  • 100% Visible Light Cut Rate

  • 99.9% Near-Infrared Cut Rate

These figures are achieved through a special multi-layered coating technology applied to the fabric. HEATBLOCK efficiently blocks heat from the sun, creating a distinct "cool space" beneath the umbrella.

Obtain genuine heat-shielding performance without sacrificing lightness. "HEATBLOCK" is the new standard for evolved parasols designed to make that ideal a reality.
