Merino Wool (100%)
What is Merino Wool (100%)?
Merino wool is a natural fiber obtained from Merino sheep, known for its softness, elasticity, and breathability. It is sourced by shearing the sheep, and then the raw wool is washed and processed into textile fibers.
Merino wool is widely used in clothing items like t-shirts and leggings due to its moisture-wicking and temperature-regulating properties. It is well-regarded in the textile industry for its comfort and durability. There is no health risk associated with wearing merino wool, but some individuals may have a wool allergy.
When you see '100% Merino Wool' on a label, it indicates that the product is made entirely from this natural fiber, without any synthetic blends.
Commonly found in: T-Shirts, Leggings, Activewear, Socks, Underwear, Base Layers
