Polo necks are a very nice part of winter clothing. Zip polo necks with a high collar are great. I'm always on the look out for pictures of these.
I like them to have a nice fine rib wool or polyester collar. Not too loose or baggy around the neck. I notice french people are really into these. I watched a french film one day and about 10 members of the cast were wearing lovely zip polo necks. This fleece is made by an Irish company called Lowe alpine but the collar is anything but...ha ha!
