Only worn once. Very cool running outer layer. Half wind blocker, half merino wool, breathable turtle neck. It is out of stock on the Tracksmith website, the final picture is the same version in gray. Website Description: The turtleneck is a winter classic for a reason. Warm and versatile, it offers neck protection and helps prevent chafing from high jacket collars in stiff winds. Our NDO version is delivered in a soft, lightweight Merino wool honeycomb jacquard with a wind-blocking panel for added protection against the elements. Wear it alone on more temperate, but windy days, or under a mid-layer or jacket for extra warmth where it matters on your core.
