I got this plow case cover a few weeks ago hoping it would help with my allergies. I didnt expect it to help with my allergies and be comfortable. The case fit perfect on my pillow. The zipper worked great but best of all it is soft and comfortable. I know with other pillow case covers I've used they have been kinda hard or very loud when you sleep.on them but this one is the best of the best. Oh didni mention it helps regulate your temp by not getting to hot all while keeping you cool. I'm definitely going to get these for everyone in my house.
