DECKA QUALITY SOCKS
A Japanese sock brand established in 2017. Rather than expressing a fixed worldview or value system, Decka embraces versatility—creating socks that naturally blend into everyday clothing and adapt to a wide range of personal styles and perspectives.











What makes it so comfortable even in midsummer?
The beanie is made using “CEFIRO,” a premium yarn that blends washi—a traditional Japanese paper fiber—with organic cotton, resulting in a highly functional material with a natural texture. Though lightweight, the rib-knit construction adds just the right amount of depth and structure.

Washi may not be the first material that comes to mind for summer wear, but it is actually ideal for hot weather. Thanks to its excellent moisture-regulating properties, it stays breathable and resists stuffiness, while its natural deodorizing and antibacterial qualities help maintain comfort even in peak summer heat.



It features a crisp, dry touch with a refreshing feel. Similar to linen, but even smoother against the skin.

The organic cotton blended into the yarn is grown without pesticides or chemical fertilizers, making it a sustainable material that’s gentle on both the environment and the wearer.





Comfortable, natural fit
Though constructed with just four panels, the moderately thick rib-knit fabric offers excellent stretch and a gentle fit around the head. The silhouette is balanced—not too shallow, not too deep—making it suitable for both men and women.



The fold can be adjusted to suit different head shapes, and it can also be worn folded or unfolded depending on your styling preference.
