Thermoball
The North Face developed a partnership with Primaloft to offer a new synthetic alternative to down.
Thermoball technology offers lightweight thermo insulation and is just as compressible as down, combining this to the optimal anti-humidity performance of synthetic materials. All this thanks to small round Primaloft synthetic fiber clusters closely to mimic down clusters; trapping heat within small air pockets to retain warmth.
