This is a lightweight jacket from DAY BY DAY JIU JITSU. It's an apparel brand often seen at jiu-jitsu tournaments in the Tokai region. The size is S. It feels similar to a Japanese size S. I purchased it around the summer of 2024. There are some slight scuff marks on the sides of the waist (likely from wearing a backpack). Please see the 6th image. Original price: 9900 yen Thank you.
