I use a Bern Brentwood summer and winter. It's a little warm in the summer, but not bad. Winter it's great. I'm in Austin, TX for weather reference.
One of my biggest concerns was avoiding the "mushroom" head look. The Bern sits pretty low on the head and the injected mold is fairly thin so it is very comfortable and looks decent.

You can find them pretty cheap online.

It's a little risky buying online, but my LBS didn't carry Bern at the time and for $30 shipped it was worth it in my opinion.
