I've had both for about a year. In the summer, i swap out the down comforter/cotton duvet cover for the blanket, which I put into a linen duvet cover. It's the perfect combination and perfect weight for me in warm weather. As for quality, I have a lot of Riley bedding and it's all holding up perfectly.

I have one of these in addition to a "summerweight" down comforter, and love them both: https://www.rileyhome.com/textured-cotton-coverlet
