Bought 2-in-1 comforter after reviewing other down and silk products from other companies. We aired it for 2 hours per other customers' and company's advice. No bad smell. Not heavy, just right amount of weight. No stitchings to keep the silk from moving around but has not moved at all. Every week for the last 3 weeks we have been flipping the front to the back. Don't see any silk movement which is great. Very soft and cozy, love it. Using the 2 layers since it's a little colder than the summer temperature. We keep room temperature at 62 F in the winter time. Will switch to 1 layer in the summer. Obviously, no feather issues. Highly recommend it.
