The technology was developed by the German company NOVONIC: four heating panels integrated into the jacket’s lining are linked to a rechargeable battery, stored in the inside left pocket of the jacket.
When you are cold simply turn on the system by pressing the button on the battery which triggers the autonomous system into a 20 minute operating cycle – these cycles can be repeated 6 times per day — to maintain optimal temperature.

Light (250g), washable, and rechargeable, the system complies with current standards.
Combined with a jacket in breathable, waterproof 20000/20000 stretch material, it will provide skiers with incomparable comfort and warmth
Skiers feel the cold sitting standing still, on ski-lifts or in particularly bad weather. 
In order to do stay warm and to make skiing more enjoyable, Rossignol launches the HIT jacket with its patented adjustable heating system.
