Here's a tip that I came up with and have been trying this year. I don't know if it will allow you to take the Monster Whitetail of your dreams this season but every little bit helps. Spray your favorite cold weather neck gator down, inside and out, with any odorless scent eliminating product such as Scent Killer or Scent-a-way and allow to dry. While on stand, keep the gator pulled up over your nose and mouth as you normally would. This will not only keep your face warm but the scent elimination product should cut down on any breath odor that you might have. Remove the gator and re-spray the outside down during the day as needed.
