The Ashmei terry looped Merino Beanie provides excellent heat management for use of those cold winter training runs.The merino content sits next to the skin and actively absorbs perspiration vapour and then releases these to the outside environment before they have a chance to condense and turn to liquid. This keeps the hat drier and therefore stops chilling which keeps you more comfortable. The mix of the merino and nylon spandex also offers some resistance to wind and water that help prevent heat loss and eventually leads to a feeling of exhaustion and fatigue. All the seams are flatlocked to prevent bulky and uncomfortable seams. Fabric: 38% Merino Wool, 46% Polyester, 16% Spandex
