I wanted to test it out for a walk, with a sub-pull protection Thermolactyl, a normal end without special property sweater and jacket. The outside temperature was around 12 ° C, with a small wind 40-50km / h., Where a wind chill of about 9 ° C.
By thus walking in my city for 1 hour, hands in the pockets of the jacket, I did not feel cold at any time. I did not get too hot either, the jacket makes me now to a temperature quite pleasant. It perfectly cut the wind. As soon as I went out of my hands pockets, I immediately felt the cold exterior win luckily the cold could not step into my sleeves.
