MIZUNO GX-SONIC Ⅲ Size is XS. Worn about 15 times in races over approximately 2 years. The marks haven't peeled off, and the water repellency is still slightly present, but there is some deterioration on the back side. I think it can be fully utilized by those who want to try MIZUNO's high-speed swimwear or those who want a number of them for practice. Please understand that this is a used item and has been stored at home.
