6 strokes to choose a real down jacket:
A down product must first have the factory name, address, contact number and other signs. If the selected down products are "three noes" products, the quality is difficult to guarantee.
Second, smell: smell whether the down products have peculiar smell. Products with bad smell are probably filled with unwashed or unwashed fillers, so don't buy them.
Third, press one button: relax the down products and let them recover naturally for 3 minutes, then hold down the down products with your hands, and then release your hands to see if the down products can quickly rebound to their original state. If they don't bounce or bounce slowly, it means that the quality of the filler is not good. If the down jacket that can bounce up quickly is fluffy, it is also warmer.
4. Touch: Touch by hand to test its softness, and see if there is a complete piece of lamb wool or long wool, feather tube, etc. That's too big and thick. If it feels soft and has a complete piece of hair, it is genuine.
Fifth, take a shot: in a bright place, take a shot of down products in the light to see if there is dust floating out. There is no dust floating out of down products, indicating that the inner layer is lined with good quality flannel, and there will be no "cashmere escape" phenomenon. If there is dust overflowing, it is made of broken wool or gray sand wool, which is generally not suitable for wearing.
Sixth, knead it: knead the down products with both hands to see if there is any plush. If there is plush, it means that the fabric is not cashmere-proof.
