Initially I was disappointed with this jacket. I thought I was buying a light, slim fitting (ie, it is Calvin Klein, slim fitting is status quo) sporty coat for spring but this is actually a winter jacket.
But this is one beautiful winter jacket. It is double zippered, and has a polyester shell. The jacket is very nicely constructed and durable. I decided to keep it as my winter jacket that I could either wear to work or for  casual. The jacket runs large and is a puffy, which was unexpected but I have grown to like it a lot.
