Like a down jacket–but without the down! The Routeburn Jacket is made entirely of synthetic materials. Its Microguard Superloft synthetic fibre insulation feels like down and delivers very good warmth-to-weight performance, and its good lofting capability makes the jacket very comfortable to wear. When it inevitably gets wet, it loses none of its insulation performance, and it dries out again quickly meaning you stay warmer for long. The Stormlock outer fabric is breathable, light and windproof making it ideal for active outdoor sports and if the rain does start to come down too hard, you can easily layer up with a waterproof shell for maximum protection.
