In the middle of summer, when the heat intensifies but the streets still look like improvised runways, the search for cool and functional clothing becomes an obsession. However, something similar happens during cold weather; people look for clothing that allows them to enjoy every moment without suffering from low temperatures.
The question is: are major brands like Zara or Mango the best option in these cases? Seasonal fashion usually focuses on aesthetics, although it doesn't always solve the real problem. People want to withstand the temperatures without losing style or comfort, and this is where technological innovation comes into play.
Space technology in your closet
What seems like a bold statement is actually a real breakthrough: the most efficient garment to fight the heat doesn't come from a runway, but from a space laboratory. It's the Outlast smart fabric, originally developed by NASA in the 1980s to protect astronauts from the extreme temperatures of space.
Although this technology wasn't initially used in space, it laid the foundation for a revolutionary invention. Outlast incorporates phase change materials, capable of absorbing and releasing heat according to environmental conditions. This way, it regulates body temperature dynamically and effectively.
From NASA to the Tour de France and beyond
The real commercial breakthrough for this fabric came at a Munich trade show, where the French company Ekoi, specialized in cycling apparel, discovered its potential. After testing it, in 2022 they launched their first collection for the Tour de France, one of the most demanding competitions in the world.
This technology allows body temperature to be reduced by up to 48.2°F (9°C), eliminating the need to unzip or change clothes during the race. Cyclists keep their focus and performance thanks to a jersey that acts like a portable air conditioner, without additional energy.
The expansion of clothing designed for space
Ekoi has expanded its use to gloves, socks, and is even developing thermal padding for helmets. This breakthrough shows that the future of fashion and thermal comfort could depend more on science than on traditional design.
Clothing with Outlast technology is no longer exclusive to elite athletes. It's gaining ground in sectors where thermal regulation is key, from bedding to everyday garments. Its efficiency and adaptability set a new standard in functional fashion.
In a world seeking sustainable alternatives and real solutions to climate change, a garment that reduces the need for air conditioning is not only innovative, it's essential. Because when science meets design, the result is fashion with purpose.
