Where to buy thermal pants? <HR style="COLOR: #ffffff" SIZE=1>Hi All, I want to buy thermal pants (for women) which I can wear inside my jeans/pants to avoid getting chilled in this weather. I have checked in so many shops near bay area, but could not find them. I dont want to buy it online as I may not be able to choose the correct size. Can someone in Bay Area help me out? Can you please name shops in San Francisco or some where near to bay area/silicon valley where thermal pants are available??
