Believe it or not, you might like wearing lightweight wool dress trousers. Riding will wear them out rather quickly, unfortunately, but I wear them a lot on a bike. They may be hot while riding, but you reach a certain temperature, and they just won't get any hotter. They also look nice. Good wool clothes drop their wrinkles very quickly, so you'll stay looking good. I get some amazing good deals on very nice Italian-made wool trousers at Costco.
