The Buff Thermonet for men and women is a multifunctional running accessory. The Thermonet fabric is four times as warm as traditional microfibre fabric and on top of that also wicks moisture effectively away. The fabric is highly breathable. Seventy percent of the material used in the construction of this Buff has been recycled. The seamless design and soft fabric provide a lot of comfort. The neckwarmer can be worn as a mask, a hairband, a headband, a balaclava, a shawl, a neckwarmer or a beanie.
