Founded in Taiwan in 1980, Oudifen is a company specializing in the production of women's underwear, with profound business experience and avant-garde design style to enter the international underwear market in France, the United States, Japan and other countries. Oudifen has provided underwear products for the 16th World Model Contest and the 32nd Miss Universe International Contest. In 2000, the hydration bag patent bra independently developed by Oudifen won the patent certificate issued by the State Intellectual Property Office.
 
The hydration bra padding is filled with a water-sensitive material, which is usually smaller than the heat of the material and is not easily deformed. The fixed hydration bladder built into the Oudifen hydration bra is cool and comfortable, which can fit the curvature of the chest and play a certain gathering role. And the hydration bra also has a thermostatic effect, which is cool in summer and warm in winter. The price of this bra is about 200 yuan, and the cost performance is moderate.
