Merino wool is the gold standard of base layers. It's warm, lightweight, and wicks away moisture. Plain wool is warm but is usually thicker—and potentially itchier—than merino legging. Cotton is warm, but will draw body heat away from you when wet, so avoid cotton entirely.
The best thermals are made from merino wool or silk fabric because it wicks away moisture, it's lightweight, and ultra-warm. People love these fabrics for travel! One of the biggest benefits of traveling with clothing made with merino wool is that it can be reworn several times without washing.
