This parka requires no complex setup; simply wear it over your chosen base and mid-layers. It is highly compatible with a variety of layering systems, from light t-shirts for mild conditions to fleece jackets for colder weather. For care, it's crucial to follow the garment's label instructions to maintain its performance and longevity. Generally, machine wash cold on a gentle cycle with a mild detergent specifically designed for waterproof outerwear (avoid fabric softeners, bleach, and harsh detergents). Tumble dry on a low heat setting or hang dry. Periodic reapplication of a DWR treatment (spray or wash-in) may be necessary if you notice water no longer beads on the fabric surface, ensuring the parka continues to repel water effectively. Always close all zippers and hook-and-loop fasteners before washing. Do not dry clean or iron.
