ThermoballTM : The new synthetic alternative to down 





The North Face developed a partnership with Primaloft® to offer a new synthetic alternative to down. Thermoball is a revolution in insulation technology. Unlike traditional, continuous-filament synthetic insulations, the small round Primaloft synthetic fiber clusters closely to mimic down clusters; trapping heat within small air pockets to retain warmth.  

Independent CLO testing has shown that Thermoball technology can offer the low weight, loft, warmth, and compressibility of down with the wet-weather insulating performance of synthetics.
