Those Cat-Ears look very interesting! One of the benefits of a thread that shares the group's knowledge.

If you run hot, a full skull cap may be too much for you, so a headband may be best. This one is made in Grover Beach, California, and for the price, makes a great stocking stuffer too! i just received one and it has micro fiber/fleece inside. https://www.voler.com/browse/product/li/1240281

they offer a thermal neck gaiter as well for $19
