These pants features a simple, highly-versatile design and are made using cotton and partially plant-derived polyester. The ribbed waist area is made using the "Steam Stretch"* technique for a comfortable fit.

*The “Steam Stretch” technique shrinks cloth by applying hot steam in order to create unique stretch materials. Special threads shrunken with heat are woven with other threads, and then only the special thread parts shrink when the steam is applied. By only shrinking the intended parts of the piece of woven cloth, three-dimensional patterns and shapes are created and the garment is completed."
