I wear these and the ihc-06's everyday of the year, cold, hot, it makes no difference. I've had this one for years and worn it in 100+ weather, easily, but I'm a dedicated hat guy, and bald, so this is a necessity….
Lord, bless this forum and all the enablers who sail in her. A random comment from me and 24hrs later I've scored my prefered colour from my favourite Osloværing @hajduk . Thanks dude!
