The new technology Thermo°Cool provides year-round thermoregulation and comfort. The yarns contain a unique hybrid fibre mix that allows garments to smartly adapt to the needs of the wearer: When you are hot and perspiring, the fabric will provide evaporative cooling, keeping you cool and comfortable. When you are cold and shivering, the fabric will reduce the exposure impact with external temperatures, keeping you warm and thermo regulated.
The Thermo°Cool combination is a unique blend of fibres with a hollow core along with fibres with a channelled surface providing benefits beyond what can be expected by just one type of fibre in a single yarn.
