As light and warm as a down gilet, but without the down, the ROUTEBURN VEST is ideal for active outdoor wear. And it’s made of recycled materials.The STORMLOCK outer fabric is breathable, light and windproof – ideal attributes for outdoor sports. The MICROGUARD SUPERLOFT synthetic fibre insulation has a similar lofting capability to down and very good warmth-to-weight performance.Light showers simply bead up and run off the surface of the outer fabric. And if the rain gets heavy, wear your hardshell over the top and keep going!
