One thing you dont want to do is underdress, youre better to put more on or carry more with you in your pack. If you get too warm you can always take some off. Try to keep your muscles warm, this is very important for bow hunting, especially your shooting arm. You did right by shooting before you went out, but heres what also helps draw your bow back a couple times every 15 minutes when in colder temps. This will help keep the muscles relaxed and warm. This has helped me become a better, more successful bow hunter.
