thermoactive underwear is tested and recommended by the leading representatives of the world's underwear. In the new version of the UYN NATYON pants, we have reduced the weight to less than 34% compared to the previous model thanks to the new design and the use of Natex bio-spear. At the same time, we were able to increase flexibility by 4% to get more flexibility. Testing in the lab and on the ski slopes has given us some new features, such as the Meta-Ribs on the kyro quadriceps to stabilize and support the kyro, and the pressure branches on the kyro's bases to protect and reduce pressure on the joints. Targeted compression, more intense in the limbs, keeps the blood flowing for later infusion.
