This is a collaboration item between COMME CA ISM and Mizuno. The fabric is thin and smooth, making it very comfortable to wear. I didn't wear it much before it became too small. As shown in the first photo, there are some slight frays near the neckline and below the MIZUNO mark. It's not very noticeable and shouldn't affect wear, but please be aware of this before purchasing. Please refrain from purchasing if you are sensitive to such details.
