Washicool

Washicool - "crisp coolness" created by Japanese paper that does not wear heat

As the name suggests, "Washicool" uses "Japanese paper. The "fiber made from Japanese paper" used in this product has better water absorbency and quick-drying properties than cotton material, and while the fiber itself is strong and durable, the "lightness" unique to paper is attractive. In addition, the moderately crisp texture is perfect for the humid season. It is an item that feels cool on the skin and does not cling to the body.
