As of right now, I have not noticed anything with these covers that would significantly alter the way the pillows feel. I'm greatful that they are not noisy as most other covers are. I also appreciate that they have very much the same feel as the covers that come on the pillows. One thing I can say so far with confidence is that even though this is an additional layer to my pillows, the original feeling, specially with the Eden cool+, has been the same in terms of coolness and breathability.

SUPER SOFT - GREAT QUALITY!

Size: Crescent Queen

This crescent pillow protector is more than I expected, as far as softness and just the overall quality of it. I wish my PILLOW was as nice as this protector! Definitely recommend.

Size: Crescent Queen

This pillow cover is everything they said it would be. Comfortable, no crinkle sound. Fits the pillow like a glove. I highly recommend.
