[pct-l] Heavier Sleeping Bag versus Lighter Sleeping Bag &Extra Clothing

[Jim & Jane Moody]

I don't know how the 9.5 * F. figure was derived, but I know from months of personal experience on the PCT and AT that a sleeping bag with a silk liner is noticeably warmer than the same bag without a liner.   How much?  I can't say for sure, but it is.

9.5 degrees how did you come to that figure?  It seems a little high. 

A silk liner adds almost zero boundary layer and if it is breathable almost zero heat retention.  A better solution would be a reflective infrared bearer like a Mylar emergency blanket but I am sure it wouldn't be all that comfortable.

Yoshi, 
Being warm isn't my only concern for comfort, Sometimes being too warm on a warm night must also be considered.  That is why I do not bring a "heavy" sleeping bag but opt for a silk liner instead to help add the warmth difference - 9.5 degrees. Read my last post on this.
