Core Insights - The article emphasizes the importance of three key indicators when selecting down jackets: fill weight, down content, and loftiness, which directly affect the warmth and insulation properties of the jackets Group 1: Key Indicators for Selecting Down Jackets - Fill weight refers to the total weight of down in the jacket, measured in grams (g), with higher fill weights providing better insulation for colder environments [1] - Down content must be at least 50% to meet the new national standard (GB/T 14272-2021), which aligns with international standards and focuses on the actual down used for insulation [2] - Loftiness indicates the ability of down to trap air, with a loftiness of 600 providing decent warmth and over 800 indicating high-quality down [3] Group 2: Tips for Avoiding Pitfalls in Down Jacket Purchases - Check the hang tag for key information, including compliance with the latest standard (GB/T 14272-2021) and details on filling materials and down content [4] - The texture of the down jacket should be soft and delicate, indicating quality; hard or grainy textures may suggest inferior materials [5] - Ensure that no down or dust escapes when the jacket is shaken or rubbed, indicating good fabric density and craftsmanship [6][7] - The jacket should have no unpleasant odors, which could indicate poor cleaning or material issues [8] - Inspect the loftiness by checking for even distribution of filling when held against light, ensuring no clumping or shadows [9]
