I am going to Iowa to hunt on Dec. 18. It will be really cold and I am looking at investing in a good coat, or coveralls. What do you guys that hunt in this cold weather use and recommend. I am from Louisiana and i probably can't tolerate the cold as well as you can. Haha. Also, what would be the best choice since I will be bringing whatever I buy back home to hunta little, meaning which one would serve better for sub-zero to 40 degree weather. Thanks.
