Muji's Strong‑Twist Jersey T‑Shirt Gains Favor as Summer Pajama in Japan

Muji's women's strong‑twist (kyōnen) jersey short‑sleeve T‑shirt, priced at ¥1,490, is being adopted as a summer sleepwear option. Made of 100 % cotton with a tightly twisted yarn, the fabric offers a dry, linen‑like feel, good breathability and moisture‑wicking properties. Reviewers note its loose fit and open neckline allow airflow, reducing the sticky feeling that can occur at night in humid weather.

The shirt is marketed in the regular women’s T‑shirt line rather than a dedicated pajama category, but consumers appreciate its versatility for both daytime wear and nighttime comfort during hot, humid evenings.
