I would dress as lightly as possible going in and carry extra clothes for when you get to your stand. Also,I have been using "Cover-Up" masking scents that are sold by Joe Skipp(who is a sponsor here)
When I hunt in the mountains,it's almost impossible NOT to sweat!!!!! I wear 1 100% wool sweater when climbing to the top,then I take it off and sit bare chested untill I cool down.Then I put on a fresh wool sweater,while I hang the other one on a tree limb to air out.If I get cold I put that one on too,over the fresh one. All of my clothes are sprayed with Cover-Up and they never smell "sweaty".
