Color: Blue Season: Spring, Summer, Autumn, Winter Size: Free Length: Approximately 50cm Width: Approximately 25cm The fabric is thin and stretchy, fitting the body comfortably and feeling gentle on the skin♪ Teijin Teviron is a synthetic fiber developed by Teijin Ltd. and has excellent features. ◎ It retains heat within the material itself, providing good insulation. 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, please refrain from purchasing if you are concerned about long-term storage.
