Unlike traditional continuous filament synthetic insulations, the small, round PrimaLoftR synthetic fiber clusters closely mimic down clusters, trapping heat within small air pockets to retain warmth. Independent clo testing by Kansas State University has shown that ThermoBallTM has warmth equivalent to 600 fill goose down. As a result, ThermoBallTM can offer the light weight, loft, warmth and compressibility of down with the wet weather insulating performance of synthetic insulation.
