This visor is as promised----WARM.  I've worn this everyday since receiving.  The temperature has been at freezing or slightly above for the passed month and I have no problems keeping the bald pate warm.  Some reviewers had concerns about a small fit but the Carhart covers my big noggin with ease.  I would have given it five stars if the visor was more substantial (too flimsy) and was extended out a wee bit more.
