I looked at this techwear bodysuit as something from the world of science fiction. But in the end I bought the UrbanFlex Pro V4 model – and honestly, it is one of the most practical purchases in recent years. By the way, I also have an unstable climate, so I can share my life experience. The most important thing is that yes, the suit really adapts. It has a multi-layer structure, but at the same time it remains very light. The top is water-repellent, the inside is a heat-sensitive material. When the body temperature rises, microporous ventilation areas are activated in the back, chest and armpits. These are not some kind of fans, by the way, everything is passive – it works due to fabric engineering, like membrane jackets, only on a different level. Tested: I walked up the Verkh-Isetskaya dam in it – I didn’t even sweat so much that I wanted to take it off. But in the cold, the suit proved to be especially cool. I stood at the bus stop for almost 40 minutes (the bus broke down), the temperature was about -2, windy. I had a regular hoodie underneath it and, you know, I didn’t freeze at all. I give it a special thumbs up for the fact that the seams are windproof, and even the hood is pulled tight, it doesn’t slip down like many jackets.
