"100 G PRIMALOFT® GOLD INSULATION: synthetic padding that works similar to goose down, but with the following advantages: • the ultra-fine fibres that make up PRIMALOFT® form a compact network of tiny air pockets able to trap body heat and keep out the cold: the excellent heat insulation thus obtained limits bulk. • the ultra-fine fibres have been developed for water resistance: they remain dry and maintain their insulating properties. • highly breathable and quick drying. • more compressible than conventional padding. PRIMALOFT® Gold Insulation Eco is made with 55% post-consumer recycled material."
