MEN'S HEAT HOLDERS THERMAL HAT GREY

Heat Holders’ warmest-ever hat is here! The new, Chunky rib Heat Holders 3.4 Tog Hat is exceptionally thermally effective, with a new Heatweaver plush insulating liner that has been developed to hold even more heat in.
The soft fur-like lining feels great against the skin (this is one time it almost pays to be bald!) and it's also very efficient at using the heat that naturally rises from your head to keep you warmer for longer.
