I was wondering what is the best exteme cold weather under cloths you can get? I got some Under Armor underwear clothing and it seems to work well but it's pricey! I was wondering if there is anything out there that will handle extreme cold with out having to look like the michelin man with multi layers on. I think the last time I was out, I have on the UA clothing, carhartt overalls, sweat shirt, carhartt jacket and my scent loc vertigo jacket for camo. I felt like I was wearing too much clothing and was a little cold still. I think temps where like -7 below zero. What is the warmest you can get with UA? Does it work? hate to spend the money to find out I am still wearing the same amount of clothing on top of it.
