If you know you will be using your hat in particularly cold weather or just prefer to be warmer, you may have it equipped with an additional, sewn-in layer of fleece, either in the form of a band going around the ears (option 1) or as a second, inner "hat" which will cover your whole head. This product can be chosen with any crocheted or knitted hat in the YourYarn shop. Please allow an additional day for the sewing in of the lining.
