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.
