Setup: The jacket requires no special setup. Choose the correct size for a comfortable fit, allowing for layering underneath if desired. The model shown is 6'0" wearing a size M, which can help gauge fit. Compatibility: This jacket is designed as an outer shell and is highly compatible with various layering systems. For colder conditions, combine it with a fleece or insulated mid-layer. For warmer, wet weather, a single base layer might suffice. Care: To maintain the performance and longevity of your Ponsa jacket: 1. Always refer to the care label inside the garment. 2. Typically, machine wash cold on a gentle cycle using a technical wash specifically designed for waterproof breathable fabrics. Avoid conventional detergents, fabric softeners, and bleach, as these can degrade the DWR finish and membrane. 3. Tumble dry on low heat or hang dry. Tumble drying on low often helps reactivate the DWR finish. 4. If water no longer beads on the surface, consider re-applying a fluorocarbon-free DWR treatment available from outdoor retailers.
