in the heat, I wouldn't want thick merino wool on. and in my experience, any thin thread 100 ones don't last that long even when babied. I do like thicker ones for the winter as base layers though
In hot (and humid) environments I refuse wear anything except merino or linen. Both dry really quickly even in the lightest of breeze. Merino doesn't even smell if you sweat, just hang it outside overnight and it's good to go.
Everything else is just a sweat sponge. Even the fanciest plastic tech materials don't work as well as merino.
