【Uses Teijin's Teviron】 Short-Sleeved Sleeveless Shirt ＊Soft and Gentle to the Touch＊ Color: White Size: F Teijin Teviron is a synthetic fiber developed by Teijin Ltd. and has excellent features. ◎ It retains heat within the material itself, so it has good heat retention. It protects the body from the cold of winter and the chill of air conditioning in summer. ◎ Because the fiber does not absorb moisture, sweat and humidity are quickly released through the gaps in the fiber. It always feels smooth against the skin, so you won't feel sticky or cold even if you sweat. ◎ Due to friction with the skin, it generates the strongest negative ions of all fibers. Negative ions are said to prevent the oxidation of blood and are good for the body. Although it is new and unused, please refrain from purchasing if you are concerned about storage at home. #Teijin #Teviron
