As the weather gets cold and nasty, so do cotton undergarments. The answer is to switch to merino wool. These have a nice, snug fit for the best functionality. We had these made in Lithuania just for us.

Merino wool, the best wool in the world

Merino wool is a fantastic choice for next-to-skin wear; most notably it feels good against the skin and retains its insulating properties even when soaking wet. So it's like regular wool, but better. Oh, and did we already mention how nice it feels?

Our merino wool undershirt is a fairly standard round neck type, with non-chafing seams, long enough hem and form fit. For those concerned, these don't itch either, but rather form a second skin.

These are moisture-wicking, dry fast, and are self-rinsing. They are also machine-washable, but washing is usually unnecessary - wool cleans itself. When not in use, air them out and give them a good shake after that. You only need to wash the clothes if you see stains or they start to smell really bad. This usually requires lots of continuous use without airing.
