Sorry gaijin42, I should have been more specific with my comment about the pockets being directed towards hiking, as very few extra clothing items are carried. Yeah, if you have something other than leaves to use for insulation, I can see them working alright. HF member "RAW" made some interesting little down pillows that were created specifically for fitting into the pockets on his Clark. If I remember right, the results were mixed. Good thread if you can find it.
