Wool is an incredible natural fiber with properties that make it the ultimate material for warm and cool weather. It’s the only material on earth that is naturally grown by mammals to regulate their body temperature and this works for us too! It is water resistant, flame retardant and since soil sits on the surface, it’s easy to clean. Wool is breathable and wicks moisture from the body when you’re warm and insulates to trap warm air near the body when you’re cold. In fact, wool can absorb 35% of it’s own weight in moisture without feeling wet to the touch. The durable wool fibers are crimped like a spring, which allows it to keep its shape even when being stretched up to 30%, this means your jacket will remain wrinkle free for a lifetime of use.
