The North Face Thermoball
The North Face and Primaloft® partnered up to develop a new synthetic insulation alternative to down. THERMOBALL™ was born and is a revolution in insulation technology.
Unlike traditional, continuous-filament synthetic insulations, the small round PrimaLoft® synthetic fibres cluster closely to mimic down clusters; trapping heat within small air pockets to retain warmth.
Independent testing has shown that Thermoball™ technology can offer the lightweight, loft, warmth, and compressibility of down with the wet-weather insulating performance of synthetics. This means that THERMOBALL™ insulates, packs down and feels like down but also provides uncompromising warmth even when wet. This versatility makes the THERMBOBALL™ your go to jacket no matter what the conditions.
