Why Merino Wool?

Merino wool originated in Spain, but Merino sheep were domesticated most recently in New Zealand and Australia. Merino sheep have very fine and soft wool, and it is not nearly as scratchy as regular wool, either, making it a great choice for a hiking, work, or running sock.

Merino wool is great as it dries fast and has antimicrobial properties. It wicks away sweat and evaporates to the outer environment. This keeps your skin dry and warm.

Synthetic fibers can absorb around 7 percent of their own weight in moisture before they feel wet, but Merino wool can hold up to 30 percent.
