The North Face M Thermoball Traction Mule V

Primaloft®: It is a synthetic fibre, originally developed for the US military, very popular in the production of outdoor clothing because of its ability to provide warmth, and thanks to its high water repellency, it excels in its thermal insulation capabilities.

ThermoBall™ Eco: Insulation technology developed to achieve thermal comfort similar to down but with the performance of synthetic fibres. The insulation is made up of small spherical fibres that trap air and generate heat even in high humidity or rain. "Eco" refers to the use of recycled materials, making it a more sustainable alternative to traditional synthetic insulation. The material is lightweight, easy to pack and reliably warm even in challenging conditions.

Textile: The textile upper of the sneakers is lightweight, breathable and comfortable, ideal for everyday wear and sports. It ensures air circulation, keeps feet fresh and adapts to their shape. Often complemented with synthetic or rubber details for durability and support.

60% Rubber: The rubber sole is a traditional and highly reliable element in the construction of footwear, valued especially for its extreme mechanical resistance and grip. This contact layer is made of natural or synthetic rubber, which is characterized by its high density and elasticity. Due to its physical properties, it provides excellent traction on a wide range of surfaces, from smooth asphalt to unpaved terrain. In addition, the rubber is naturally waterproof and resistant to temperature fluctuations, ensuring stability and a secure stride in a variety of climatic conditions.

40% Recycled rubber: It represents a sustainable path to high performance with minimal environmental impact. This material is created by processing used rubber, for example from industrial surpluses or old tyres, thus closing the production cycle and saving primary resources. Despite its ecological origin, it retains excellent mechanical properties such as flexibility, abrasion resistance and reliable traction. It is the ideal choice for modern footwear that combines functional design with responsibility towards the planet.
