If you're looking for an insulated jacket for your next hut-to-hut walk but you don't want down, this jacket is a great option. The ROUTEBURN JACKET is as warm and light as a classic down jacket, but is made entirely of synthetic materials.The MICROGUARD SUPERLOFT synthetic fibre insulation feels like down and delivers very good warmth-to-weight performance. It also has good lofting capability, which makes the ROUTEBURN JACKET very comfortable to wear. Even if it gets wet, it loses none of its insulation performance, and it dries out again quickly.The STORMLOCK outer fabric is breathable, light and windproof - ideal attributes for active outdoor sports. The jacket can be layered up or worn as a standalone. In wet weather you can wear it under your hardshell.
