Back to 100% Cotton! What Makes MUJI's "Warm Cotton Innerwear" Different?
Previously, I introduced "Cool Cotton Innerwear" as a hit product for summer from MUJI. At that time, what became clear was the overwhelming trust in "cotton". And now, this season, the winter item "Warm Cotton Innerwear" has been updated, with the phrase "This year, it's 100% soft cotton" being promoted.
"100% Cotton." This truly reflects the company's philosophy and is what consumers expect the most. Therefore, we spoke with Iori Takagaki from the Clothing & Goods Department and Ryo Oyamada from the Production Development Department to discuss the power of "cotton" and the appeal of "Warm Cotton Innerwear."
