Breaze pillowcases use AromaCap technology to provide a continual release of aromatherapeutic vapours all through the night while you sleep. Both sides of Breaze pillowcases are infused with millions of microscopic liquid-filled capsules. Each capsule contains Breaze vapour oil; a blend of natural essential oils known for their aroma therapeutic properties. As your head comes into contact with your pillow and moves during sleep, the micro-capsules rupture releasing a continual burst of vapours to help you breathe easy and get a better night’s sleep.
