I live in an area that is so cold that we call base layers long underwear because it is exactly that. I wake up and put on my base layers every day just like underwear. So Ive tried them all. Here is how I rate them. Backcountry Merino wool base layers are my number one overall choice for warmth, looks, pilling and wear, no-ich, no-smell, and still looking great wash after wash. A close second is Kari Traa 100% wool baselayers they are super beautiful however the embroidered label on the leg starts to ich during hiking. They are just slightly less warm but are equal for all other areas. The original Smartwool Merino wool comes in third but they are terribly plain to look at and dont launder quite as well. I wont repurchase the Smartwool Intra-knit version again as it is unforgiving on the skin particularly knees and elbows and pills after washing. They can become sweaty and not very warm especially at altitude. Terramar polyester baselayers cause unwanted and problematic moisture in your private areas, dont buy them. Terramar wool baselayers are warm but very itchy. Just as a side note I tend to cold wash and line dry my baselayers.
