I wore some leafy stuff turkey hunting this year and it worked real well on the gobblers. Never have tried it for deer hunting. Another option Talon is to use a compression sleeve, from CamoSkinz. I wear one whenever I have bigger clothes on. It is like a real long glove with no fingers, goes from your thumb to your elbow and fits snug, keeping all your clothes tight to your body. Here is the link to it at the Cabelas site. I also wear the gloves by the same company and love them. They are real thin so you still have great tactile sensitivity.
