senz° CoolTech: All-Weather Protection and Cooling
Learn how senz° CoolTech fabric in the Stormproof Umbrella reflects infrared radiation to keep temperatures lower underneath.
senz° CoolTech: Stay Cool and Protected in All Weather
As global temperatures rise due to climate change, spending time outdoors is becoming increasingly challenging. Hotter summers and more frequent heatwaves make comfort and protection essential — not just from rain and wind, but also from intense sunlight and heat. At senz°, we developed CoolTech, a high-performance fabric used exclusively in our Stormproof Umbrella. By reflecting infrared radiation, CoolTech keeps the space beneath the umbrella noticeably cooler, providing protection from sun and heat, in addition to rain and wind. The Stormproof Umbrella with CoolTech is more than a practical shield from the elements — it’s a smart, climate-conscious solution for anyone seeking comfort and safety outdoors, whether walking in the city, traveling, or enjoying nature.

How CoolTech Works
CoolTech manages heat and moisture while providing full protection against rain and wind. Its key features:
- Reflects infrared radiation: Reduces heat absorption so the area under the umbrella stays cooler.
- All-weather protection: Effective in sun, heat, rain, and wind, making it a versatile companion.
- Moisture management: Water-repellent and quick-drying fabric keeps you dry during showers.
- Stormproof stability: Combined with the umbrella’s aerodynamic design, it resists strong gusts and maintains structure.
Why Cooling Matters
Rising temperatures mean prolonged sun exposure can be uncomfortable or even unsafe. Traditional fabrics absorb heat, increasing temperature underneath. CoolTech reduces heat buildup, creating a cooler, more comfortable space and helping you enjoy outdoor activities safely.
CoolTech in Extreme Heat
CoolTech was originally developed to keep users cool in hot and sunny conditions. During events like the Olympic Games in Rio de Janeiro, where athletes face intense sun and high temperatures, traditional umbrellas can quickly become too warm to provide comfort.
The senz° Stormproof Umbrella with CoolTech reflects infrared radiation, keeping the space under the umbrella significantly cooler than standard umbrellas. This allows for rest and recovery in the shade, making a noticeable difference during warm-ups, breaks, or while waiting outdoors.
At the same time, CoolTech maintains the umbrella’s stormproof, water- and wind-resistant performance, offering reliable all-weather protection. Whether facing sun, heat, rain, or wind, the Stormproof Umbrella provides comfort and safety, making it a smart, climate-conscious solution — used even by TeamNL at the Olympic Games.

Conclusion: Smart, All-Weather Comfort
The senz° Stormproof Umbrella with CoolTech is more than a rain umbrella. It is a climate-conscious tool that:
- Keeps the space underneath significantly cooler by reflecting infrared radiation.
- Protects from rain, wind, sun, and heat.
- Delivers comfort, durability, and style in all weather conditions
