Perfect as a merino baselayer or as a lightweight jacket.  At Prois, performance fabric choices are EVERYTHING. We believe the cornerstone to the best outdoor gear lies in its fabrics. Merino wool is far superior to the synthetic fabrics available on the market and we have sourced the highest quality merino available.  Merino wool is naturally anti-microbial, odor-resistant, moisture-wicking, offers UV protection, is naturally static resistant, and the fibers are much finer than traditional wool.
