If you're active in the outdoors during cold temperatures, a good set of base layers is crucial. Merino wool is superior to all other fabrics including synthetics, cotton, and silk. owing to its moisture management properties. The wicking process of merino wool moves moisture and sweat away from your skin, to the outside of the garment, spreading along a larger surface area where it can dry more effectively. This keeps you dry as you sweat, and helps regulate your body temperature as you heat up during activities and then cool down during rest times for all-day comfort. This is the reason merino wool undergarments are so popular. Composition: 100% merino wool. 100% authentic made in New Zealand.
