PrimaLoft was originally developed in the early 1980’s under contract by the US Army as an alternative to goose down, which loses its insulation properties when wet. PrimaLoft proved to be an excellent insulation for combat clothing and gear due to its technical superiority. The US Special Forces selected PrimaLoft insulation as part of a multi-layer Protective Combat Uniform (PCU) system as well as for sleeping bags and gloves.
