Brand PrimaLoft®

PrimaLoft® is a water-resistant synthetic-down insulator developed for the U.S. Army in the 1980s.

Brand Primaloft

Before 1986, the U.S. Army used goose down to fill military uniforms and sleeping bags. A synthetic alternative was developed to match the properties of down – in terms of weight, warmth, density and compressibility – but would also retain its performance when moist or wet. The resulting PrimaLoft® was commercially launched in 1989 and is used for insulation in cold- and wet-weather clothing and equipment.
