From one of Japan's leading underwear and clothing makers, the Triumph Joppari Japanese Sake Extract Thermal Underwear for Women is a comfortable solution to staying warm in the winter. This item is made from Japanese sake extract processed from sake lees, which help retain and absorb heat better. (Joppari is an award-winning type of sake from Rokka Shuzou, a brewery in Aomori Prefecture.) The materials are also very stretchy, so they will fit snugly around your body. The black inner wear is available in two sizes and turtleneck or open neck versions.
