Thermoball

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.

Benefits
  • Lightweight
  • Phenomenal warmth in cold and wet conditions
  • Packs neatly into zipper pocket (not all styles)
  • Insulates even when wet
