Work great during turkey season but I've been wearing them the last few weeks while making sure I have shooting lanes at some old and new spots because it's the only long sleeve shirt I dare wear. I come out of the woods looking like I've been swimming in the creek. They work well for moderate sweat but they can reach saturation pretty quick in this heat and humidity. But I am a sweaty beast, even in the dead of winter I will walk in usually in just a tshirt and won't add layers until I'm up my tree and cooled off.
