My morning hunt was 30 yrds from a creek and in a very moist environment. Needless to say the skeeters were bad, but once I had my leafy suit (basically leaf shaped material stitched on mesh) it didnt let the skeeters through. I had my face cover on, a mesh one, and had the hood of my leafy pulled over my hat and as far down on my forehead as possible. The mosquitoes were there but couldnt infiltrate my "bug suit" so instinctly I didnt react to them....just let them do their thing and it didnt affect my ability to shoot if I needed. I dont own a thermocel, but found out my "bug suit" was just as affective.
