ISG stands for "Insulated Shell Garment". It is a multifunctional jacket which emerged from the military special forces area. The merger of softshell outer layer with the G-LOFT® insulation makes the ISG jacket a real "hybrid". The excellent heat storage capacity of the G-LOFT® fiber and the water-repellent, windproof and breathable properties of the 3-layer softshell outer layer gives this jacket its distinctive character.
