The Omius cooling headband in black combines a lightweight, ergonomic design with innovative cooling technology for enhanced comfort during sports activities in warm conditions. It comes with 20 patented cooling elements that rest directly on the skin and support the body's own cooling process. The cooling elements are made of porous graphite with a hydrophilic coating. They absorb moisture and enhance evaporation, effectively dissipating heat. The enlarged surface creates a noticeable and lasting cooling effect as long as the cooling pieces remain moist and air can circulate. The headband itself is made from an elastic material blend, providing a comfortable and secure fit even during movement. The cooling pieces can be easily removed if needed and combined with other Omius products.
