Eliminating boundaries. An "umbrella" redefined by its function.
There used to be a clear distinction between parasols and rain umbrellas. Parasols were characterized by their cool, airy textures, crafted from natural materials like cotton or linen, and valued for their breathability. In contrast, rain umbrellas were tools made of nylon or polyester, designed specifically to repel water. Carrying a different umbrella for each type of weather was the standard practice.
In today’s urban environment, however, that boundary is quietly fading. The catalyst for this change is the rise of "high-performance blackout umbrellas," born from the need to combat the intense heat of recent years.
The "all-weather" structure brought about by material evolution
Most modern parasols now feature a coating, such as polyurethane, on the reverse side of the fabric. In our development, we aimed not only to block the sun but to physically shield the user from infrared and visible light. The multi-layered coating required to achieve this "100% blackout" specification physically fills the gaps in the fabric, resulting in excellent waterproof performance.
While the "water-repellent" ability to shed rain in beads depends on surface treatment technology, the film on the reverse side effectively prevents water penetration. As a result, today’s superior parasols possess the inherent potential to serve as highly reliable rain umbrellas. While "all-weather" umbrellas were previously just rain umbrellas with a UV coating, they have now evolved into top-tier parasols that offer exceptional waterproofing as a functional benefit.
The rationality of choosing a "parasol" even on rainy days
There are two rational reasons to choose a high-performance parasol (an all-weather umbrella) on a rainy day—reasons that those who appreciate well-crafted tools should know.
The first is protection against invisible UV rays. Even under a rainy sky, about 30% of the UV radiation from a sunny day still reaches the ground. 100% blackout fabric efficiently cuts these scattered rays, helping to reduce the impact on your skin, regardless of the weather.
The second reason is ease of maintenance. Models with a structured, crisp fabric due to their coating, such as our HEATBLOCK series, shed water easily; a light shake after use is enough to remove surface moisture efficiently. This makes them easier to dry thoroughly after use in the rain, which helps prevent deterioration from moisture and keeps the tool in excellent condition.
The potential of a 365-day companion
The perception that "parasols are for sunny days only" is now a thing of the past. What we propose is an umbrella as a "device" that allows you to comfortably control your immediate environment, regardless of the weather.
Lowering your perceived temperature under harsh sun while protecting you from sudden rain—choosing one such all-weather tool is a smart way to minimize your belongings and improve your quality of life. An umbrella that quietly performs its function by your side, no matter the season or the color of the sky. Modern umbrellas have evolved into just such a reliable presence.
