Hi. They do get hot with the liner, most folks says to take the liner off but it takes the premiumness out of it if you know what I mean. The holes on the side do help though.
@@akubraandwhatnot8084 This is a city/dress style hat, though some wear it for working. If you want the unlined working hat try the 'Cattleman', or the same hat crown shape as the Coober, but larger brim working hat, check out the 'Riverina'. I have three Riverina hats, two Territorial, and one Pilbara. I love larger brims.
