My Heavy Weight (1980s) -vs- My Lightweight (2004) Gear
The following is a comparision of what I took on a week long trip in the  80s (heavy weight)  -vs- what I bring now. I expected the nights would likely get down to 30F, with the daytime ranging 45-60F. Items which have a hot pink background are more "comfortable" or I enjoy using more.
