Price reduced!! Unused, authentic YAMAHA motor touring biker jacket, Monster Energy TECH3 jacket, featuring a black and green color scheme with 360-degree logo embroidery. - Brand: Monster Energy - Model Name: TECH3 - Color: Black/Green - Material: Polyester - Features: Biker-oriented design, logo embroidery Size S, but this is not a Japanese size. I believe it's a Japanese M size. I am 170cm tall and weigh 65kg. My chest measures 96cm, and it fits perfectly with underwear + shirt + vest. It has some give because it's made of stretch fabric. I bought it two years ago, but it's too flashy for a 75-year-old like me, so I've kept it in my closet. I'm selling it now as part of a decluttering effort. If you're interested, why not take this opportunity to buy it? The original price was 27,800 yen, so I'm offering it for 15,000 yen, including shipping. I'm looking forward to your comments. Thank you for looking.
