Lighter shading and heat shielding. A high-spec parasol that combines 100% shading with lightness.
The HEATBLOCK pentagon addresses the challenge of "heavy parasols that block sunlight effectively." By combining unique shading technology with ultra-thin fabric, it achieves high shading and heat-shielding performance while being lightweight enough for daily carrying.
[3 Key Features]
-
Blocks sunlight with "100% shading and heat shielding"
Uses fabric with 100% UV cut rate (UPF50+), 100% shading rate, 100% visible light cut rate, and 99.9% near-infrared cut rate. The product's heat shield efficiency is measured at 87.3% (※Test result for Sand White). -
Lightweight design, starting from 119g, for easy carrying
Some of the frame (ribs) use lightweight and elastic carbon fiber. It is finished to a light weight of approximately 119g to 147g (varies by color). -
Frame structure resistant to wind speeds of 15 m/s
The frame uses flexible and highly elastic carbon fiber. It has durability that passed a wind resistance test of 15 m/s (0 degrees front) by a third-party organization.
[Commitment to Functionality and Quality]
-
Easy folding due to thin fabric
By using thin fabric woven with 20-denier ultra-fine yarn, the thickness characteristic of shading umbrellas has been eliminated. It is characterized by being flexible, soft, and easy to fold. -
High water resistance and lasting water repellent performance
Uses fabric with water resistance exceeding 13,000mm, which is higher than the standard for general umbrellas. The water repellent performance maintains an initial score of 90 points and 85 points after 20 washes in tests based on the AATCC 22 method.

When it comes to highly functional sun umbrellas with light-blocking properties, the fabric tends to be thick and heavy. Conversely, if lightness is prioritized, they become vulnerable to wind. We set out to resolve this contradiction between "functionality and lightness" and develop an umbrella that could be carried in a bag daily, rain or shine.
The base pentagon series for rain umbrellas adopts a manually opening type with fewer parts to prioritize lightness. However, for this HEATBLOCK pentagon, we intentionally chose an "easy-open/close type" structure, which increases the number of parts and thus the weight.
Since light-blocking fabric is thicker and stiffer than regular rain umbrella fabric, it places a greater strain on the ribs and stitching during opening and closing. If we only pursued numerical lightness, we could create a lighter umbrella with a simpler structure. However, to achieve both sufficient durability as a sun umbrella and a smooth folding experience, this easy-open/close structure was essential.
We also implemented improvements to enhance the strength of the frame in detail. For the connection point between the main rib and the stretcher, instead of a hollow "grommet" for weight reduction, we deliberately used a stronger "solid rivet."
Though a small, inconspicuous part, it is a crucial element for firmly supporting the taut light-blocking fabric. Combined with the resilient carbon fiber frame, this structure is lightweight yet can withstand wind speeds of 15m/s.
The completed HEATBLOCK pentagon achieves a lightweight design while maintaining 100% light-blocking performance. By keeping it in your bag, you can smoothly handle sudden rain or strong sunlight. We hope it will be a tool that comfortably supports your daily commutes.
