Our Chelonia 150 Shellaclava is a moisture-wicking fleece neck warmer with an attached hood comprised of our 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.
