Cotton & Silk Rib Series

An underwear series crafted from MUUGI’s original Cotton & Silk Rib Knit.

Our original rib fabric is made from a blend of fine extra-long staple Supima cotton and silk, combining the soft fullness of cotton with the smoothness of silk. The result is a gentle, comfortable texture against the skin.

The slightly airy, cushioned feel comes from the natural softness of cotton, while silk adds suppleness and a subtle luster to the fabric. Because the rib is knitted with a moderate density, the fabric has just the right amount of kickback, allowing it to stretch and return to form. Designed to be flexible without feeling too tight, it offers a stress-free, comfortable fit for a wide range of body types.
