I am a big believer in breath control and have been since way before gumoflage came out, I used to chew spermint gum and go face mask with great results. I think that breath control along with a good scent control regimen can reduce your scent profile to near minscule levels. When i first began to practice this, i was amazed at how many deer got directly down wind of me and never knew i was there.

On a personal note:
A few years before Gumoflage came out I contacted a non hunting buddy of mine who worked for Wrigley at the time and proposed the Idea to him, I tried to twist his arm but he just didnt get it and YaYa'd me. Fast forward about 4 yrs and Gumoflage comes out....I forward him the link and say hey, look what I found for $5 a pack....

He kicked himself in the stones and i gave him a follow up one for good measure.
