This is a warm-up wear, a Lin Dan model, that should have been released around 2015. It's already discontinued, so it's likely difficult to find. I bought it and wore it a few times, then it was stored in a drawer. I checked it myself and found no moth-eaten spots. It was used for less than six months, and I think the condition is good. Since it might have a smell from the drawer, I washed it again to make it clean.
