By removing the traditional black jersey outer lining of our Supertherm® neoprene we have created a softer and stretchier Beanie with all the thermal properties that neoprene foam provides. The resulting garment provides an excellent fit, warmth and comfort next to your skin. The band around the head is double thickness to provide a secure fit and additional warmth around the forehead and ears. The single thickness fabric over the top of the head has more give and stretch for a proper fit. There is an elastic loop attachment point on the Beanie so that you can secure it to your clothing.
