To be honest, I wasn't expecting much from these considering the low price, but they are great! They aren't bulky, zipped smoothly, they washed well (read the instructions) and easily fit our overstuffed king size down pillows. I used them inside linen pillow cases and the terry seems to keep the pillow "in place" nicely. Oh, and there's zero noise or smell from the waterproof liner. Very pleased with this purchase!
