Wash well, dry well, keep it longer
Well-cared-for technical clothing keeps its warmth, water repellency and breathability for years. Here is the method for puffer jackets and for skiwear, in three steps.
No dryer: lay it flat on a drying rack, with air on both sides, patting and turning it regularly. Allow several days to get the full loft back. Never on a radiator.
Reviving water repellency: after 6 to 10 washes, use a dedicated water-repellent detergent or treatment, available in specialist stores. A regularly cared-for garment keeps wicking away sweat: the membrane's pores stay open.
