I know it is only August and the last thing you guys are thinking about is keeping warm, but I was watching TV and this chick gave a tip to keeping warm during cold weather bowhunts. She recommended using ThermaCare Heat wraps, which you can get at any drug store. I've never used them but thought it was a pretty good idea. My question is do they have a strong scent? I'm pretty sure a lot of these kind of products smell like BenGay. Maybe some of you guys have used them and can speak to how they might work.
