Week End Elastic: anti-slip reinforced fabric device. A brand new concept, the Week End Elastic is mounted on the tires of the driving wheels, adhering perfectly to the tread. Thanks to the special fabric and to the studded reinforcements, the Week End Elastic significantly increases the car's grip to ice and snow and is the ideal solution for vehicles with reduced space between tire and mechanical parts. It is assembled and disassembled with great ease and is kept in a convenient bag that does not take up space in the trunk. Washable in water or in a washing machine!
