GX・SONIC III MR M size Mizuno's competition top model Thank you for viewing. Please read the profile before purchasing. MF is a type for middle and long distances. I am selling it because I retired from swimming. This is a past model of Mizuno's GX sonic series, but I purchased it because the buoyancy was introduced on the channel of the swimming YouTuber "Hima na Ojisan". It has a good overall balance, including buoyancy, and I have a track record of using it in the 100-meter freestyle final race and achieving my best time. It was my competition swimsuit for when it really mattered. Used about 10 times. After use, it was washed with water and stored in the shade. The water-repellent effect is still present as shown in the photos. Although there is some overall wear and tear, there are no tears and the logo is in good condition. I have managed it as much as possible, but it is a used item, so please understand this before purchasing. If you are considering purchasing multiple items, I will also offer a discount, so please let me know in the comments section. High-speed swimsuit Competitive swimming swimsuit Racing swimsuit
