This 5X is an excellent hat through and through. The feel and attention to detail are very good. I have a few hats and this one is one of my very favorites. The brim is perfectly straight, a very nice detail. The rigidity is even better than expected. I really am impressed with the way this thing is put together and looks. The page here doesn't show much detail and Bailey might give more on their site but I will write down here that the sweat is a nice medium thickness leather. Light tan color. Lining is a similar light tan color and nicely done. Very glad I rolled the dice and may do it again in the Steel color. I own Stetsons, other Baileys, Akubra, Dobbs, Beaver brand 10X in Ginger color. I have a nice little collection and was not sure what I might get in this one. I have the brown and its a very good choice.
