This hat may look a bit odd at first since it has a brim on a winter cap, but it's great.  It keeps your head really warm and offers a bit of extra protection for your eyes from sun, snow, rain etc.  The materials it's made of are top rate as with any Carhartt product.  It's basically a bit of a fancier version of the US Army jeep hat which is still issued today.  I happen to have a couple of those too.  It's a great winter hat, pick one up.  Some reviews say that it's tight depending on head size, but over time it breaks in and if not give it a little stretch and help it break in.  Great purchase!
