Not a medical device
HatNapN® is a comfort and travel accessory. It is not a medical device, and it is not intended to diagnose, treat, cure, or prevent any condition, including any sleep disorder. If you have concerns about your sleep or your health, talk to a qualified healthcare professional.
Use common sense about when you use it
HatNapN covers your eyes. Never wear it flipped down while driving, operating machinery, cycling, walking, or doing anything else that requires you to see. Do not use it in any setting where you need to be aware of your surroundings for your safety or anyone else’s.
Installation and your hat
HatNapN attaches with an adhesive backing and is designed for a one-time installation. You install it at your own discretion. We recommend testing on a hat you are comfortable modifying, and contacting us first if you have questions about a particular hat. HatNapN is not responsible for damage to hats.
Results vary
How well HatNapN works for you depends on your hat, your surroundings, and how much light you are trying to block. Reviews on this site reflect the honest experiences of individual customers and are not a guarantee that you will have the same experience.
