I bought this cap for my husband who had been looking to replace his old baseball caps with this type of cap and he absolutely loves it! He says that it feels a bit snug but not tight and judging by the way he looks wearing it, I think it actually looks like a good fit on him (He normally wears fitted baseball caps which measure between 7 1/2"-7 5/8"). He looks so handsome in his new cap and is so happy with it. The only complain I have is that it only comes in black :( but other than that the cap is everything he was looking for at a fraction of the price of those other name brand driver's cap. Now I cannot comment as far as how warm it is because A) I don't wear it and B) It hasn't been too cold yet for him to opine on how it holds up against the cold New England winters, (will have an update when it gets colder).

UPDATE: It has been about two months since I bought this cap and it has been cold as $*** lately and this cap has not held up to these freezing temps all too well. For the price not a bad cap at all just don't expect it to get you through sub freezing temps.
