Buy the coldest Under Armour you can get! Get the hoodie also! I know I thought I wouldn't like it but I love it! Get the socks, put them on first then put a regular pair on over them. I wear just a pair of tennis shoes and my feet stay warm.
Got my wife the whole 9 yards also! She is always cold! LOL one morning heading to the lake about 3 am it was about 26 degrees, she had the air on in the pickup plus her window down and I was doing 70 mph!
Sure cuts the wind!
