Calvin Klein Black Gray Tweed Blazer Sport Coat Jacket 46L check measurements

Calvin Klein Black Gray Tweed Blazer Sport Coat Jacket 46L check measurements My husband isn’t sure what size this is but I believe this is a 46L because the measurements are the same as the two chaps sports coats that he had that I have listed that are size 46L however I cannot find a size or content tag. I believe this is wool but I’m not 100% sure. This is in excellent condition, the pockets and the back vent slits are still tacked down, and the stitching has not been removed. We bought this at Macys and it might have been worn twice before the office went more casual.
