This is a ZIM +BA riding jacket, a brand formerly produced by RS Taichi. It's made of steerhide leather (cowhide). I bought it in 2009 and used it for touring, probably less than 10 times. It was described as suitable for heights of 175-185cm, with a chest size of 96-104cm and a waist size of 82-90cm. At the time, I was about 173cm tall and weighed 80kg, and with a chest protector underneath, I could just barely zip it up. Without the protector, it felt a bit loose. It weighs about 2.4kg, and while it feels heavy when you wear it, it gives a sense of security. It has a removable back protector. As you can see in the photos, there are some stains and signs of wear, but I think it's still wearable. I stopped riding a few years ago, and although I kept it for sentimental reasons, I've decided to sell it.
