Group 1 - The core viewpoint emphasizes the scientific selection of down jackets based on insulation parameters and wearing methods, highlighting the importance of the filling material in creating a "static air layer" for warmth [1] - Goose down has superior insulation due to its higher loft, while duck down offers better cost-effectiveness [1] - The key indicator for down jackets is the fill power (FP), with recommendations of 500-600 FP for urban use, over 700 FP for cold environments, and above 800 FP for professional polar activities [1] Group 2 - The outer fabric of down jackets should be windproof and water-resistant, while the inner layer should focus on breathability [1] - A layering suggestion known as the "sandwich method" is recommended: the inner layer for moisture-wicking, the middle layer for warmth, and the outer layer for wind protection [1] - Proper maintenance, including hand washing in around 30°C water with neutral detergent and air drying after gentle squeezing, can significantly enhance the jacket's cold resistance [1]
