Care & Longevity

Hand wash or machine wash at 30°C using liquid detergent or a specialist cleaner, then tumble dry on a low heat with a slow spin speed. Store in a cool, dry place away from direct sunlight to help maintain insulation loft and garment performance. Always follow the manufacturer's care instructions and avoid treatments that conflict with the care label.
