Wife loves this shirt.
looks great, extremely comfortable.
Perfect for working out in the cold, Not too thick that you get hot and need to remove it leaving you cold. But not too thin that it leaves you overly cold until you start getting warm with exercise.
I wouldn't wear this as a casual piece when very cold though, would still require a jacket over it, Definitely meant for training in without risk of over heating.
Just an average chilly day this will still be plenty warm though.
