What are people actually wearing under the Klim Freeride pants? I know Klim says you have to wear the 2 speciality Klim layers under the pants for warmth. But what I'm looking for is a pair of pants to wear when mountain riding that are not big and bulky. Wearing 2 layers plus the Freeride pants sounds like it would defeat the purpose of trying to get away from bulky bibs. Any experiences welcome. Thanks.
