I purchased 4 pairs of these & was pleasantly surprised at the quality & the great price. Especially when you see & price the ones in the stores & the price is usually per panel it can really add up. They are a nice weight with a silky feel to them. Definitely darkened the room. The only surprise to me was the back of the curtain was not white like most thermal or lined curtains. It's just one piece of material that does it all.
