Merino Wool boasts countless natural properties that render the fiber a top choice for anyone looking to work or play in the great outdoors. Most notably, Merino Wool's unparalleled breathability, warmth-generation, softness (softer than regular wool due to finer micron fibers), moisture wicking abilities (literally vacuuming sweat straight from the skin, keeping you warm), and anti-microbial (odor-free) qualities rank it the world's best natural fiber. And unlike synthetics or cotton, there is an extremely finite quantity of Merino Wool in the world, which explains why many companies opt for the easier, cheaper route. Not Duckworth.
