I'm happy with these...especially god solution for travel pillows that tend to get dirty in the car. The fabric is comfortable and the zippers keep your pillow fully enclosed regardless of size. Also a good place for kids to contain their pj's or stuffed toys.
You can probably find a cheaper dollar per pillowcase protector item, (with some hunting involved), but it probably won't be as of good quality. For this level of quality and durability I would have to pay $**-**locally. Most protectors in this price range I have looked at are either to plasticity, flimsy, and more junky than I care to have in my house hold. This item at the price I paid for it (with a nice overstock discount on my whole order) was a online shopping find.
I finally purchased pillow protectors that work and feel good. I'm glad I purchased these in Queen instead of Standard since our pillows are more lofty than usual and definitely easier to put on. These wash up well and dry quickly. They retain their shape. What I like best was the value for the money. I'm always looking to save so this was a great find.
