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.
