The Old Spice Fresh I have is in the old porcelain OS bottle, and is an after shave. I bought it about 7 years ago. It is an excellent scent! Highly underrated!
However, I'm wondering if we're talking about different fragrances, because the OS Fresh I have smells nothing like Calvin. I remember Calvin being an ultra-spicy aromatic fougere. OS Fresh (the one I have) is a sharp fresh citrus, sort of like a stronger, less refined Eau Sauvage in a way. It's citrusy and soapy, and just excellent.
