A 100% post-consumer recycled polyester, ThermoBall Eco is “The New Synthetic Alternative to Down.” It provides the lightweight functionality of a standard down jacket with the added wet-weather insulation of down alternatives. Retains loft and traps heat, no matter how wet your environment is. Unlike traditional, continuous-filament synthetic insulations, the small, round PrimaLoft® synthetic fiber clusters closely mimic down; trapping heat within small air pockets to retain warmth.
