This is a Kendo uniform made from a fabric called Tetronnit-Sillead. It is designed to prevent the uniform from becoming heavy with sweat, dries quickly after washing, is stretchy, and has a soft feel.

[From Toray's website]
Tetronnit-Sillead is a 100% polyester knit fabric developed by Toray, boasting excellent sweat absorption, quick-drying properties, and stretchability. Its special dimple structure ensures good skin separation, superior breathability, and drape, making it ideal for apparel linings, sportswear, and Kendo protective gear (inner lining of men and kote).
