Grown by Merino sheep, Merino wool is thinner and softer than regular wool, which makes the Vycah Maxx Merino Wool Socks easy to wear next to the skin. Besides the natural comfort, this material also helps to regulate body temperature, helps keep your feet dry and sweat-free, and can even be odor resistant. In addition to the wonderful properties of Merino wool, the Vycah Maxx Merino Wool Socks also feature Nuyarn technology which has been shown to be up to 35% stretchier, 25% warmer, 16% stronger and 5 times faster drying as traditional ring-spun Merino wool. As a result, you'll find the Vycah Maxx Merino Wool Socks will become your favorite pair whether it's for everyday use, a toasty early season scouting trip or a frigid late season hunt.
