Cleared wind speed of 30m/s. An all-weather model with excellent wind resistance and heat shielding performance.
TOUGHNESS was born from the pursuit of wind resistance in folding umbrellas. In wind tunnel tests conducted by an external organization at 0, 135, and 180 degrees, it demonstrated high robustness that prevents damage even at a wind speed of 30m/s (*1). It supports comfortable outings on rainy days and sunny days.
【3 Key Features】
-
Wind resistance that cleared a 30m/s wind speed test
High robustness that recorded no damage in multi-directional wind speed tests at 0, 135, and 180 degrees (*1). Its robust rib structure prevents damage from strong building winds and sudden gusts. -
100% light and heat shielding, triple blocking sunlight
Blocks 100% of UV rays, 100% of visible light, and 99.9% of near-infrared rays (*2). The black interior absorbs reflections from the ground, and the black color exhibits an 84.6% heat shielding effect (*3), blocking the intense heat of the scorching sun and reducing the perceived temperature. -
Combines a 60cm rib size with robustness
A large 8-rib design that widely covers rain and sunlight. It uses a thick central pole and reinforced parts, providing stable use even on windy days.
【Commitment to Functionality and Quality】
-
Withstands repeated inversions
Polycarbonate resin is used for the stretchers that receive wind. The structure is designed to withstand 100 inversion tests and repeated opening and closing, pursuing quality that allows for long-term use. -
High water resistance and lasting water repellency
Measures over 13,000mm in water pressure resistance. Water repellency maintains 90 points initially and 85 points after 20 washes according to the AATCC 22 method. It proves high durable water repellency through "Easy-Dry."

(*1) This is a measurement result in a test environment and does not guarantee durability against all sudden gusts in an actual use environment. Additionally, we define this "robustness that clears 30m/s wind speed" as the strongest standard for our products.
(*2) Each cut rate is a measured value for the fabric condition. Due to the structure of umbrella seams (stitching, etc.), slight light leakage may occur.
(*3) This is the inspection result for the product (finished product).
After repeatedly witnessing umbrellas flipping inside out and breaking due to strong winds and gusts in the city, we set out to develop a "durable folding umbrella that resists damage even when inverted by wind and can be used for a long time." This led to the development of the frame structure for TOUGHNESS.
To strengthen the joint sections, which are a weak point of folding umbrellas, we arrived at the design concept of "flexibly deflecting stress." Instead of confronting strong winds with rigid strength, we intentionally allow the umbrella to bend flexibly to parry the force of the wind. By adopting highly elastic polycarbonate material for the stretchers, we established an ideal structure that absorbs the impact of wind and prevents damage.
The completed frame structure demonstrated wind resistance in wind tunnel tests conducted by an external organization, proving it would not break even under 30m/s winds from angles of 0, 135, and 180 degrees. Furthermore, it passed a rigorous "100-time inversion test."
Despite its large size with 60cm ribs and 8 main spokes, we combined a thick central shaft and reinforced parts that firmly withstand wind pressure, creating a robust frame that can be used stably even in gusty conditions. This umbrella provides peace of mind for use on windy days and in adverse weather.
