My Locale Oregon and Washington
About Me I started hiking about 45 years ago. My first backpack was 40 years ago. I currently try to do one backpack trip of 5 nights every month (which can be tricky in the winter) 20 to 50 miles. Mostly I stay around Mount Hood, Columbia Gorge, Mount Adams, Goat Rocks, and the Olympic Peninsula. In recent years I have shifted to lightweight - my pack weight without food and water is about 15 lb (7 kg). I make a lot of my own gear - silnylon tarp-tent, bivy, synthetic bag, simple bag style pack. My sleeping pad is a Therm-a-Rest air mattress.

Re: sleeping naked
If I have marginally enough insulation, my feet will get cold. The body automatically restricts blood flow to feet to keep torso at temperature, but then the feet are cold.

If you were an "M" or "Mlife" person you could read articles by Roger, me, and Matthew Morrissey on how to measure : )

Re: Re: Interesting
to prevent sloshing around of down, I think cell width should be twice the loft maybe twice isn't the perfect ratio and a sligthly different value is better. Probably a lot of range in that...
