I've been rethinking my base layers since Form posted. I moved to Ice Breaker 260 about 3-4-5 years ago. When I sweat, they get pretty wet. I think the issue is drying time after I stop or take a stand. They do seem to dry in the arid west but not so in the humid east. I have some thinner hybrid base layer tops I use when I'm just hiking. One by OR is my fav.

I've looked at the FL aerowool and Kuiu Peleton 130 as options. I'm headed for 3-4-5 days of deer hunting in S TN next week. There will be extensive hiking/climbing. I'm going to test a couple lighter synthetics vs Merino to see what I think.

This sidebar has been interesting.

Adversity doesn't build character, it reveals it.
