In our podcast with Sai, he told us about the Fundoshi, and if you were curious here is GX3 Gloss Touch Fundoshi. Here is what they say about it.
Chic and stylish design and glossy luster! GX3 [fundoshi -FUNDOSHI-] suitable for the current era. The highly elastic, smooth and glossy fabric creates a voluminous silhouette that you will want to show off. It is a T-back type that can be easily worn through the legs, so it can be worn easily. Adopts a material that is soft to the touch and stretchy. The rubber around the pouch provides a sense of volume and hold. The braided rope-shaped waist strap is 12mm wide, which emphasizes masculinity. Because it is “flat”, the surface does not stand out even when wearing clothes.
