The Vest has 5 heat levels with a special heating cell system made out of bio-thermal-fibres which are incorporated in the backside of the clothing. The synthetic heating cells can hardly be felt through the flexible bio-thermal-fibres; therefore it is very comfortable to wear the jacket. Fire increases your wellbeing at cold temperatures; therefore you won’t want to miss Fire when in the cold.
