I like the Pearl Izumi Ultrasensors also but they are kinda pricey. You might want to check out www.velowear.com. They sell Voler cycling clothes and have a free exchange policy if it's the wrong size. So far I'd say on a comfort level the Voler stuff is as good as Pearl Izumi but probably not quite as durable. I haven't had my ultrasensors very long but I know some guys who have pairs that are many years old. Right now I'm just pulling a pair of tights over my shorts when it's colder out. I'm thinking about picking up some leg warmers and trying that aproach though.
