Now that the weather is cooler I purchased a pair of Specialized long biking pants from my LBS. they have a thin fleece lining and are warm. However, there is no padding in the seat area, and therefore gets uncomfortable on longer rides. Do the long pants normally come without padding, didn't notice it when I bought them. I feel I still need the padding provided in a normal biking short. Should I wear the shorts under the long pants? Anyone else have this issue?
