Engineered by Gordini to combine the warmth of wool with the comfort and wicking superiority of fleece, Lavawool in independent tests outperforms 100% wool and leading synthetic fabrics. How? Lavawool utilizes the inherent insulating properties of wool to keep you warm; but, unlike pure wool, which absorbs and retains moisture, Lavawool wicks moisture quickly from your skin and garment with its patented weave of synthetic fibers and wool. This marriage of fibers is the Lavawool advantage — keeping you drier and warmer wherever your cold weather adventures take you.
