About Red Card, Authentic Tokyo Denim: http://redcard.tokyo Denim pants in slim straight silhouette. Waist which is not too constricted inside reduces tightness. Using the fabric which uses Supima cotton and has soft texture and high stretchability, it features a high kickback and helps prevent the knee part from sticking out. The silhouette is hardly affected by body shape by using 11.75oz fabric. Using Pima cotton warp yarn achieves a softness when worn and the dyeing method, “GrandBlue,” dyes indigo deeply into the core and provides a shade gradation.
