The Rho Lightweight Wool Neck Gaitor from Arc'teryx is a practical substitute for a scarf. The sleek neck warmer is made of very soft, high-quality merino wool. It offers all the benefits of wool - odor control, temperature regulation - and a plus on top of that: unparalleled comfort and cozy warmth. And best of all: unlike a scarf, it lies flat against the neck, doesn't slip and is hardly noticeable.
