Re: [pct-l] Insulation

[Bighummel@aol.com]

Will the micro holes in Polarguard (and possibly other synthetic insulation 
materials of which I am not so familiar with) retain insulation value when 
compressed under your body? Obviously a significant part of the insulation 
value is the ability of the fibers to hold or trap air still.  If all of the 
available space between fibers is eliminated then the insulation value will 
certainly be reduced,  but what about the micro holes in the fibers 
themselves?  I suppose there isn't enough vertical density of fibers when 
compressed to be of much value.  

With the quilt, is it attached on the sides to the foam insulation?  What 
happens when you turn over in the middle of the night?  Or is the quilt roomy 
enough to allow you to turn your body without turning the whole quilt/pad?  I 
toss and turn in my sleep and sure like that when I do there is insulation 
whichever way I go and the pad stays on the ground.  I worry that the quilt 
will allow air channels to form from the sides to your body if you don't lie 
still and flat.  Any comments from those that have tried the quilt idea?

Just the musings of an old fool.
