Friends got me a jacket and an outdoor insulation turtle neck. Very helpful in the winter hunts. I've been using them every year for at least three years now.
You can find these things at Cabela's, Joe's Sporting Goods (St. Paul, MN), Ganger Mountain everywhere, or Mills Fleet Farms in your town--wherever that is. lol Don't go to Walmart. There's no quality there for sporting goods except fishing lures.
