I have a variety of smartwool clothing. Most of them I find comfortable next to my skin, and all of them I acquired with that intention. I use them for skiing, biking, backpacking, and etc.

I wash them as needed, without regard for instructions. Because of my lack of care, some of them pill. They are base-layers, and I am okay with this. None have shrunk significantly, and none have exploded, vaporized, or otherwise been damaged. A few socks have gone to wherever socks go to.

I also have a pair of smartwool armwarmers, which I absolutely love. I find I need arm an extra arm layer more often than I need an extra torso layer.
