Setup, Compatibility & Care
To ensure your jacket performs at its best, adjust the hood and hem toggles for a snug fit when you anticipate heavy rain. The Koster is designed to be worn over light mid-layers, such as a fleece or long-sleeve base layer. Regarding care, always wash the jacket in cool water with technical garment detergent to preserve the waterproof coating. Tumble dry on a low setting or air dry, and periodically refresh the DWR coating if you notice water no longer beads up on the surface. Avoid using fabric softeners, as these can strip away the breathable performance of the technical fabric.
