Cats Paw brand, Japanese Heavy Flannel

I hate to get rid of this shirt but I dont think I will ever fit in to it again. I bought this during a trip to Japan and It is used but in like new condition. “Cats Paw” is the Japanese brand and its an heavy weight flannel. It is a regular fit and a Japanese size Large. Which is in between a USA med/large. If you know Japanese flannels, you know these arent cheap and the craftsmanship is unmatched.
