Review: Great pillow tick - Second set that I have bought. Great pillow protection, I like that the zipper isn’t exactly on the end and the edges are tucked in. They wash great and fit bulky pillows
Review: So far I really like them. - These are nice very crisp and cool cotton pillow protectors. They are a little on the bigger side making it very easy to slip my fluffy queen size down feather pillow inside but I would have preferred them to fit a little better. I know they were an in bigger in length and width but I thought they would shrink a bit but they didn't. I washed them in hot water and dried them on medium heat and they came out great but still just a bit too big. Once inside the pillow cases they don't look bad though as you can see in the photo. I do kinda wish I had tried the standard size but I was worried they would be too small. Because they are such a crisp cotton they do make a little noise when you shake them (see video) but once it's on your pillow with a pillow case you don't really notice it. They do seem like they will protect pillows well since they are such a tight crisp cotton. Since my down feather pillows are so expensive and I don't like waterproof protectors on down pillows I usually use 3 protectors on each pillow for extra protection. Two of these together on a pillow seem like they would really help protect my pillows especially with an additional cotton pillow protector under these. I know, I know it seems excessive.....I just like clean pillows. Lol Overall these are fantastic pillow protectors that are the perfect thickness and feel very durable and like they'll last a long time. All 3 zippers on the protectors are smooth and feel durable. I don't think they are water resistant so I'm not sure why it asks about that.... Reviews are important to me because I rely so heavily on them when making purchases. So I try to leave thorough reviews for other customers. I hope this review was helpful.

### ⭐⭐⭐⭐⭐ Exceptional quality 100% heavyweight cotton
*by C***A on December 2, 2025*

I ordered a set of 2 in the standard size, and couldn’t believe the heavyweight quality for such a reasonable price. I have very expensive 750 fill goose down pillows that are almost too big for standard protecters/cases and these went right on with no struggle. Even stayed true to size with no shrinkage after washing/drying. The weave is so tight they were still incredibly stiff I was a little worried they would be uncomfortable. But that doesn’t negatively affect the feel of the pillow or outer case at all. The zipper is super sturdy too. And is well placed so you don’t feel it. These protecters will definitely keep your pillows clean and prevent yellowing. I will be ordering enough for all the pillows in my house! Honestly, I wouldn’t have imagined being this excited about purchasing pillow protectors
