Never one place. Always one jacket. A breakthrough in alternative down, The North Face Thermoball provides ultralight warmth in all conditions. Watch this video to learn more about ThermoBall’s breakthrough design.
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.
Thermoball benefits include:
- Thermoball Collection features Thermoball insulation technology
- Lightweight
- Phenomenal warmth in cold and wet conditions
- Just as compressible as down
- Insulates even when wet
