First... I pre-ordered this stuff just to see, because I want them to work.
However; If it is supposed to be a warm weather hunting garmet, using merino underneath it kind of defeats the purpose, for me... I sure hope these garmets do not stink after working up a sweat because I am in need of something to stalk pronghorn in that is very breathable.
Merino works well for hot weather. It wicks away moisture from you and it doesn't stink like other moisture wicking fabrics.
