Lightness as the standard for all weather conditions. HEATBLOCK Pentagon 2025 model pre-orders now open

Whether it's a bright sunny day or a sudden downpour, weather preparation is always what weighs us down. Parasols are heavy, umbrellas are bulky, and lightweight umbrellas are unreliable for durability... Pre-orders are now open for the 2025 model of HEATBLOCK pentagon , a product that makes the compromises associated with folding umbrellas a thing of the past.
Experience the new everyday life brought about by this fusion of aesthetics as a tool and high specs that can withstand harsh environments.
Overwhelming defensive power hidden in a thickness of just 0.1mm
The core of HEATBLOCK Pentagon is the proprietary "HEATBLOCK" fabric, which doesn't just block light. It has a multi-layer structure that physically blocks ultraviolet rays, visible light, and near-infrared rays, which are the source of heat.
With 100% shading, it feels like you're carrying a shade with you. Even on days when the glare from the asphalt is intense, a quiet and cool space spreads out beneath the umbrella. The ultra-thin fabric, woven with ultra-fine 20 denier threads, is surprisingly flexible, making it easy to store.
Ultimate lightweight design with guaranteed reliability
To overturn the common belief that "light umbrellas are weak in wind," we paid particular attention to the frame material. We chose carbon fiber, a material trusted in the aerospace industry.
At just 119g, this watch is much lighter than a smartphone, and the moment you pick it up, you'll feel a sense of freedom. But behind its lightness lies its incredible durability, able to withstand even the strongest winds.
Furthermore, we have made no compromises when it comes to functionality in the rain. Thanks to its powerful water-repellent finish, it repels raindrops and allows you to wipe off the water with just one shake. This is proof that it is a true all-weather jacket that you can easily carry in your bag on sunny or rainy days.
The 2025 model: Experience the evolution in your hands
The 2025 model offers a sophisticated color palette that blends in with urban life. The lineup of four colors harmonizes with any lifestyle, from business to weekend leisure. The wide "wide band" allows you to quickly and beautifully pack your umbrella, even when you're in a hurry.
