Comfy soft pillow covers
Color: 02 - White, Size: Queen (20" X 30"), Color: 02 - White, Size: Queen (20" X 30")
Absolutely love these pillow cases! I bought 2 sets. After I received them & washed & dried them they did remain wrinkly. I just went ahead and put them on my pillows & the wrinkles went away. I continue to love the feel, coolness & comfort. Will definitely buy more.

Sleek shear soft cool zippered pillow cases
Color: 07 - Green, Size: Queen (20" X 30")
I'm a huge fan of bamboo fabric. It feels great to wear and so it also feels good to sleep on, especially during hot and or humid spells. Pillowcases came in a pack of 2 and were well packaged and arrived undamaged. Shipping was very fast. Cases appear to be well made. they are a lovely soft green which is perfect for a restful bedroom setup. As expected the fabric is soft and relaxing against the skin, it seems to retain a cooler feel than cotton.Bamboo tends to be a thinner fabric that is light and once damp, dries pretty quickly. Perfect for folks who run hot normally and need extra cooling during the summer or people who sweat at nigh. Cases are zippered and zippers worked well and appear nicely sewn in and decent quality. At night, slept very well. I think this is a good product and like the price point a lo. Will be looking to get another set very soon!

Soft, luxurious pillowcases
Color: 03 - Navy, Size: Standard (20" X 26")
Great quality, soft, luxurious material. Love the way these zip up to keep pillow from falling out. The weight of the material is pleasant—somewhat like the bamboo material. The rich navy blue color is beautiful. Great value and very durable.
