The new aynthetic 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.
• ThermoBall Collection features Thermoball insulation technology
• Lightweight
• Phenomenal warmth in cold and wet conditions
• Packs neatly into zipper pocket (not all styles pack into zipper pocket.)
• Insulates even when wet.
