I have not spoken to anyone who has used these wraps.  My own wraps are
becoming a motly collection and I thought this year might be the time to
try to evaluate the effectiveness of the insulation.  When unwrapping I
thought I could rate the wraps as 1, 2, or 3 as to the apparent
insulating quality left and see what the survival rate is for all of these.
 
Any ideas?
