Just my .02c for Eastern woodlands in the three seasons.
There are some very good points made from both sides of the wool vs. synthetic debate.
Whatever one decides to choose, it should work for them.

That might be an oversimplified statement, but there are too many variables to say this is better than that, in ALL environments. There's too much difference between seasons and from Alaska to Texas.
I will wear wool early spring and mid fall through winter, but most don't wear it in the summer. Can you die of hypothermia in the summer? Yes.

The other point when I was on a mountain when no rain was in the forecast reminded me of something. A storm moved in and I was far from shelter. I brought plenty of provisions, but didn't consider a tarp or poncho. The storm changed suddenly at the last moment right after I asked the Lord for help.
It was a close call.
