It's easier to lose body heat through your head in winter than any other part of your body, so it's worth investing in a good quality thermal hat to keep yourself warm… but there’s no reason that it can't be pretty too! With a signature wolf fur-effect pom-pom, the Heat Holders Heat Weaver Cable Knit Pom Pom Hat is attractively knitted from marl yarn, but not any yarn. It’s the same Heat Holders thermal quality as the rest of their range, and lined with gorgeously soft Heat Weaver fur fleece, that retains body heat in the fibres to keep you warmer. Plus of course, it feels lovely against your head!
