Fine Wool Snood - also known as a circle, loop, or eternity scarf, an infinity scarf does not have a beginning or an end. It is one continuous, long strip of fabric that can be wrapped around the neck several times. This creates a look that is slightly different than the typical scarf. The comfy, relaxed vibe makes them popular accessories during the fall and winter. Infinity scarves are made from a 100% fine wool fabric.
