Micro downlike fiber is made from polyester but very similar to down, has similar soft and cushy feel,. It’s fine and smooth in feeling, but can provide good supporting. Comparing to real down, it doesn’t make molds or worms, more easier to be taken care, and finished products(pillows,duvets) can be washed and dried by machine directly. It’s widely used in down jackets, ski shirts, duvets, sleeping bags, etc.
