Great duvet insert
Size: King, Style: Light
Perfect duvet insert. I got a pretty expensive duvet to cover this and they worked great together. The fit was perfect and I didn’t feel like the duvet was smaller than its cover. This was a cheap option that keep us warm while not being too think. This product is also breathable and recommend if you live in a place that transitions from hot to cold often.

Great mid-weight comforter
Size: King, Style: Light
Great comforter, especially for the price. I put it in the dryer for a bit when I first got it and it became nice and fluffy. Perfect mid-weight duvet.
