gotta go with cardeer here....hunt near water. and real early .......as for sweating....its cooler near the ground......ground blind??? Also buy your hunting clothes to fit a lil looser..that will help. ive seen guys have to suck it in .to button up...thats got to be making you hot ..not to mention uncomfortable.....maybe use baking soda to absorb sweat. on neck area and crotch area especially.. wear headband to soak up sweat and keep out of eyes..I dont recommend a hat because it stops the heat from venting off you...I use a camo bandana......Some days its just too damn hot....but you can kill em from da couch..Whew... Sorry I coulnt come up with anything...HEE HEE
