In this paper, I subject base layers in various weights made from merino, merino blends, and alpaca to the suite of tests I have developed to evaluate base layer performance. I then compare the performance of these base layers with those of the polyester base layers I have recently reviewed. We also see if my preconceived notions about merino hold water. Finally, we will see how to choose the fiber for our base layers.
Learn how to choose a base layer for backpacking, base layer material performance differences, and how base layers impact moisture transfer in the broader context of a clothing system.
