Set of 2. Although these are new and unused, the packaging has become soiled during storage, so I've bundled them together. There are no issues with the product itself, but please purchase only if you understand this. (The price has been slightly reduced.) Color: Yellow 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 fibers. It always feels smooth against the skin, so you won't feel sticky or chilled even if you sweat. ◎ Through 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.
