I recently bought some expensive pillows and want to protect my investment. As a lifelong allergy sufferer, I looked to allerease. I really like these pillow protectors. They zip up smoothly to fully enclose your pillow and prevent allergens from getting on it. I love that the fabric is soft and has temperature control built in. I have no idea how it works, but it does! They launder well, and as a bonus are anti-microbial.
