By the description I thought these were all cotton, but when arrived, they are cotton/poly mix. Not a huge deal, but not what I was expecting. I love the design and the quality is soft and satiny. I have not washed it yet, so we'll see how it holds up -- but from what I can see I don't expect a problem.

Pros: Great value
Cons: Hard to tell which way is up (long or short side) for inserting the duvet and positioning on bed.
