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
