The Chelonia 150™ Shellaclava™ is a moisture-wicking fleece neck warmer with an attached hood comprised of soft and warm midweight fleece. The thoughtful design allows for you to stay warm and dry from all angles, with a seamless transition from the Double-Layer neck warmer to the breathable hood. It can be worn under a helmet or hat, and features flat seam hood construction which joins the double-layer fleece neck at the back and sides to keep wind and snow off your neck and out of your jacket.
