Our bodies emit heat in the form of Infrared (IR) waves. These waves will usually be trapped by a hat as the heat gets absorbed into the fabric and starts to make you sweat.
Rather than being a barrier to trap in heat, OURA headwear fabrics are synthesized with IR emitting ceramics fibers which naturally emit IR energy to enhance microcirculation. The fibers improve body circulation and metabolism to keep your head warm.
At the same time, our caps are ultra-breathable, allowing any excess heat to escape and keeping your body temperature regulated so you never overheat.
