Technologies:
- ThermoBall™ ECO: The North Face™, in partnership with Primaloft®, offers a new synthetic alternative to down. Thermoball™ is a real revolution in insulation technology.
Unlike the continuous filament of traditional synthetic insulation, PrimaLoft®synthetic fibres are thin and round, similar to down fibres, and retain heat in small air pockets. The ThermoBall™ technology combines the advantages of down in terms of lightness, warmth, loft and compressibility with the insulating properties of synthetic fabrics, even in wet weather.

- OrthoLite®: The soles are made of open-pore polyurethane. To put it simply, it is a foam membrane! This honeycomb sole design wears less quickly than traditional soles, draining moisture more easily and absorbing impact better. Footwear with this technology will keep feet warm and dry, protecting against bacteria and fungus while improving performance through shock absorption and minimal wear over time.
