Here in CO we are fortunate to have mountains. If it's too hot in the city it's usually perfect in the mountains.
My "minimum" gear is: FF helmet, mesh or perforated leather jacket, gloves, jeans, boots. I do not wear riding pants if it's hot. With a t-shirt underneath my mesh jacket I stay reasonably cool unless I'm in stop-and-go traffic.
