UNDERSON UNDERSON
Launched by the MASH Group in 2019, known for operating Cosme Kitchen and Snidel among others, UNDERSON is an underwear brand. It focuses on "Japanese undergarments made from washi paper," utilizing washi fiber in many products to maximize the inherent properties of washi such as water absorption and quick-drying capabilities.







Weaving Japanese Tradition and Technology into Washi Fabric
They employ "WASHIFABRIC" 1/56 bare jersey fabric, woven thinly using fine yarns. It offers a smooth and silky touch unique to washi, a lightweight and comfortable fit, and excellent stretch for comfort.

Furthermore, the exceptional breathability of washi used directly on the skin ensures no clinging even when sweating, allowing for a comfortable experience.

Like cotton, these items are washable at home, ensuring ease of care. For maximum utilization of washi's properties, it's recommended to use non-silicone detergents during washing.



Washi and the Circulation of Forest Environment
The world-renowned multifunctional material "WASHIFABRIC" is born from environmentally conscious production and processing. Mature trees, whose CO2 absorption rate decreases, are processed into building materials. The leftover parts from this process become the raw materials for WASHIFABRIC.

Under appropriate forest management, the growth of young trees absorbs more CO2 and produces oxygen, completing the cycle of forest environment.
