I used my Allerese pillow protector. I have very bad allergies and I wanted to use a pillow protector that gives me the maximum protection.  My pillow stays cool and I don't get hot.  It's very soft and does not have that stiff feel that other brand pillow protectors have.  I really like the softness.  I normally use white sheets so I like that i do not have to use a pillow case because this product is white and soft enough to sleep on very comfortably.
