ISG stands for "Insulated Shell Garment" and now in version 2.0, the ISG has proven itself popular with professionals all over the world. ISG 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.
FITTING NOTES: This jacket is a tailored fit and is snug around the torso. Most customers have found they need one size up from thier MIG or HIG size.
A jacket of exceptional quality and functionality. Does not look awry on the street, but more than capable of handling work out field (or the range). As noted, the jacket is a tailored fit and can be snug with base layers on (although I have not had an issue with a small). Definitely has me hooked on Carinthia and will not be shopping any other brand from here on out. Service from Cool Kit was equally exceptional.
