National AllergyPremium 100% Cotton Zippered Pillow Protector - Standard Size - White - 3 Pack - 300 Thread Count - Hypoallergenic Bed Pillowcase with Zipper - Breathable Encasement Cover

The material is 100% cotton. A must. The zipper is sturdy and worked as expected. The price was very reasonable for cotton. Material was also a good heavy weight. Not thin. I would definately buy these again.

Well made with zipper close. Soft and silent fabric. Easy to wash and install over pillow. Size is good.

Pillow protectors are really important for your investment in good quality pillows. Wetness from sleep can easily seep through a pillowcase and leech into the cotton fabric casing of your pillow, making it stained or yellowing the overall color over time. Considering that a really good goose down feather pillow can go between $70 and $140 on average, spending $10~$20 on a very good pillow protector is just smart thinking.I've gone through about two dozen pillow protectors over the years. What usually happens is that the fabric isn't as resilient as expected and will end up yellowing over time. I often forget to launder mine, remembering once every few washes. In some cases, the protector will reach a point where it's not providing enough of a barrier and allow staining moisture to sneak past. Or, the zipper ends up breaking.I finally decided that buying cheap pillow protectors to throw away every couple of years is just not smart. This time I invested more. This pillow protector set by National Allergy was on sale, so I got two for $13.50.The first thing I noticed is that the fabric is a bit stiff. But this is something that softens up over time, thankfully. It does have a cotton-like shell that feels like good quality. On the flipside, there's a treatment of some kind that feels like it's water repellent, without being a sort of all plastic 100% waterproof barrier. It does breathe. The zipper is not along the edge, but instead about an inch back from the edge on one side, which is a smart design--reduces stress on the zipper teeth.One thing that kind of surprised me. This is a queen size, but it appears to be 20" by 31". I happen to have a "short queen" that's in between standard and usual queen, coming in at 28" long. So, I end up with 3" extra material. It's not a huge deal, because I fold that over and push that through the pillow case first. The fold stays, it lays flat, and the pillow feels fine. Because it takes a good long while of use to figure out if a pillow protector is going to hold up, I'll have to come back at a later point to follow up.

I don't know who this pillowcase is for, they are so big

For years as soon as my head hit the pillow one nostril would plug up, then the other and soon I'd be waking up gasping for air several times through the night. I was tired all the time. Even with my scent free bed sheets, shampoo and nose rinse before bed, nothing worked. I suffer from allergies and sinus issues and I never thought that dust mites might be causing this because they had no scent. LOL I saw a review on amazon about this and purchased this pillow case.The first night I tried it, right away I noticed that both my nostrils were open and I could breath. I have been sleeping restful every since I got it. I'm not tired in the morning anymore because I'm breathing better at night. I have a king size rubber pillow and this case fits it well. It seems the zipper is cheap but it hasn't broken and it doesn't bother me when I'm sleeping.I highly recommend this product for people allergic to dust mites
