I like that they actually worked to protect my pillows from nightly sweats. I took them of my pillows to wash, they had some stain on them, but not the pillow. I was happy. They held up really well in the wash and I hung them to dry; I did not put them in the dryer. I'm sure you could on low, low heat. They seem like good quality, they have a good zipper. My only complaint is that they open halfway the long way and I had a hard time putting my pillows in them, they should re-think that. All the ones I have purchased before zip on the short side making it easy to put the pillow in. The fabric is soft and keeps sweat and dust off the pillows. They do not make noise like some, so I don't keep waking up when I move around. They are an overall good value and a good choice.
