11 reviews

Our eyelids are translucent which means even the smallest amount of light at night can impact melatonin levels and sleep quality. With today's modern world we are surrounded by light pollution; street lighting and indoor technology cause tons of light pollution during the night., keeping a pitch black sleeping environment is near impossible! 

Using the Deep Sleep Delta Sleep Mask  completely eliminates 100% light entering your eyes, this creates "pure darkness" for your brain, which then increases your Deep and REM sleep.

We have custom designed wider and deeper memory foam eye cups that allow you to fully block 100% of light hitting your eyes while still being able to open and close them. Made with super soft, breathable, and durable materials that gently cuddle your face without putting any pressure on your eyes.

Conventional sleep masks don't always fit all head shapes ans sizes; The Deep Sleep Delta Sleep Mask has adjustable eye pieces that velcro on and off so you can position them exactly to your face shape ensuring the perfect fit.


  • Large memory foam eye contours that are fully adjustable to suit all face sizes
  • Wider and deeper eye spacing- zero pressure on eyelids or lashes.
  • 100% light blocking design for increased deep and REM sleep.
  • Contoured design making it suitable for back, belly and side sleepers
  • Adjustable non-slip headband with micro velcro keeps the mask in place all night

An absolutely brilliant buy and

An absolutely brilliant buy and a must for anyone needing pitch black at anytime they're needing to rest while there's light invading the space. I've used mine on a flight and most nights my fiancé reads at night or watches TV. Worth every penny

Love it!

It genuinely blocks out 100% of the light around you, and is super light and comfortable to wear. A PROPER sleep mask - miles ahead of anything you’d buy in a shop or get an a plane!

So good

This mask is the best I’ve ever used. I sleep in every position and this mask stays put keeping everything so black. My only problem is my husband constantly stealing it!

As a third shift worker, sleeping during the day is a challenge. The adjustable, lightweight, total light blocking sleep mask ROCKS!!! I have slept better in the weeks since purchasing the mask than I have in years! My attitude over all has improved, with quality sleep. I highly recommend the Deep Sleep Delta Sleep Mask to anyone who needs comfortable assistance blocking out light. Thank you!!!

Total blackout

I work nights and use blackout curtains in my bedroom but sometimes I want to have complete blackout. The Delta Sleep mask certainly delivers. I found it to be comfortable even with side sleeping. I thought the mask was a great price, especially for such a quality product. I would definitely recommend it.

Sleep mask should be renamed 'ZEN' mask!

I love the softness and comfort of this mask. I wear them to sleep as well as during my daily meditations. I couldn't be happier with the quality , comfort and flexibility of this mask. Also the staff is extremely helpful in tracking the parcel which was lost in the post (not a fault of the company) and promptly sent out a replacement. 5 star to product and service. Thank you
