How these picks were made: by comparing published specifications and clearly-credited public reporting. We do not run a laboratory, we have not measured these products, and we do not claim to have slept with them. Here is exactly how we choose.
Short version: buy a flat mask, not a contoured one. The Alaska Bear silk mask is the pick - thin, cheap and light enough that it does not shift when you turn your head. If it leaks at your nose, the Mavogel adds a bendable nose wire without adding real thickness.
Why the usual recommendation fails here
Nearly every “best sleep mask” list is topped by a contoured mask with molded eye cups, and for back sleepers that is correct - cups are the most complete way to block light. Face down, the same design becomes the problem.
- Your head weighs about 11 lb and it is all on the mask. A rigid cup pressed into a pillow does not deform; it transmits that load into the bone around your eye socket.
- Cups lever the mask off your face. The pillow pushes the cup sideways, the strap resists, and the seal breaks at the nose - the exact leak you bought a contoured mask to avoid.
- Turning your head drags the mask. Stomach sleepers turn from one cheek to the other several times a night. A high-profile mask catches on the pillow each time and walks up your face.
The published guidance from mask testing is consistent on this: stomach sleepers want the lowest profile they can get, in the region of 15-16 mm, and light construction so the mask does not get displaced by movement. That is a flat mask, full stop.
What to look for instead
- No molded cups. Anything that stands proud of the face is out.
- Low weight. A lighter mask stays put through a head turn. The silk masks here weigh almost nothing.
- A flat strap, positioned away from the ears. A buckle or a knot sitting behind your ear is bearable on your back and painful face down. Alaska Bear’s headband-style design moves the adjusters away from the ears, which is the specific reason it tops this list.
- A nose seal that does not add bulk. A bendable wire, as on the Mavogel, closes the nose gap while staying flat.
The part a mask cannot fix
Face-down sleeping brings problems a mask has no view on: neck rotation held for hours, and pressure on the face all night. Our page on sleeping positions covers what actually changes if you can move off your front, and it is worth reading before you spend on gear that works around the position instead.
If you are shopping because a streetlight or a partner’s lamp wakes you, also check whether the room is the cheaper fix - mask versus curtains and the dark-bedroom guide both start there.
What about a weighted mask?
Skip it. Weighted masks work by resting mass on the face, which is precisely what you already have too much of when you sleep face down. They are a back-sleeper product - our weighted mask page is honest about who they suit.

All three are flat masks with no molded cups, because a cup pressed into a pillow transmits your head weight straight into your eye socket.
Our top pick · The cheapest mask genuinely worth owning
1. Alaska Bear Natural Silk Sleep Mask
A flat silk mask that costs less than lunch and blocks a surprising amount of light - the honest default before you spend more.
- Material:
- Natural mulberry silk shell
- Profile:
- Flat - sits against the face
- Strap:
- Elasticated, adjustable
- Packability:
- Folds to nothing
What it gets right
- Almost nothing to feel against a pillow, so side sleepers get on with it
- Silk is kinder to skin and lashes than a foam contact surface
- Cheap enough to keep a spare in a bag
Where it falls short
- Flat masks touch the eyelid, so you cannot open your eyes underneath
- Light leaks around the nose on most faces
- Silk stains and is easily damaged in a hot wash
Skip it if: You need genuine blackout for daytime sleep. A flat mask will not get you there.
Pick 2 · A flat mask with a real nose seal and no cups
2. Mavogel Cotton Sleep Mask
Layered cotton with a bendable nose wire - it closes the gap beside the nose that plain silk masks leak through, while staying flat enough to lie on.
- Material:
- Layered cotton and modal over an elastic foam core
- Nose seal:
- Built-in bendable strip you shape once
- Strap:
- Adjustable, fits roughly 19-29 in
- Profile:
- Flat - no molded eye cups
- Care:
- Hand wash; travel pouch included
What it gets right
- The nose wire closes the one gap that ruins cheap masks
- Side wings keep pressure off the temples
- Flat enough to sleep face-down on a pillow
Where it falls short
- Hand wash only, which people ignore and then regret
- The strap pills and wrinkles over months of use
- The fabric rests directly on your eyelids
Skip it if: You need to blink or open your eyes under the mask. That takes a contoured mask with cups.
Pick 3 · Travel, and anyone who finds standard masks too narrow
3. Drowsy Silk Sleep Mask
An oversized silk mask with a wide wrap-around band - the extra coverage seals the temples where narrow masks leak.
- Material:
- Mulberry silk with a padded interior
- Coverage:
- Oversized - extends past the temples
- Strap:
- Wide band, adjustable
- Profile:
- Soft and low, though bulkier than a plain silk mask
What it gets right
- Temple coverage is the reason it outperforms cheaper silk masks
- The wide band spreads pressure instead of cutting a line into your head
- Comfortable enough for a long-haul flight
Where it falls short
- Premium price for a mask without molded cups
- Bulkier than a plain silk mask in a bag
- Contacts the eyelid, so no blinking underneath
Skip it if: You want zero eyelid contact. Buy a contoured mask with cups instead.
Questions people actually ask
What is the best sleep mask for stomach sleepers?
The Alaska Bear natural silk mask. It is flat, very light, and its headband-style design keeps the adjusters away from your ears, which is what makes it tolerable face down. If it leaks beside your nose, the Mavogel cotton mask adds a bendable nose wire without adding real thickness.
Can stomach sleepers wear a contoured sleep mask?
Not comfortably. A molded cup pressed into a pillow transmits your head weight into the bone around your eye socket, and the pillow levers the cup sideways until the seal breaks at the nose. Contoured masks are a back-sleeper product.
How thin does a sleep mask need to be for sleeping face down?
As thin as you can get - mask testing points at roughly 15-16 mm of profile as the practical ceiling for face-down sleeping. In practice that means a flat fabric mask with no molded cups, which is the whole shortlist on this page.
Are weighted sleep masks good for stomach sleepers?
No. A weighted mask works by resting mass on your face, and sleeping face down already presses your full head weight into the mask. They suit back sleepers.
My mask keeps riding up when I turn my head. What fixes that?
Lower profile and less weight. A mask that stands proud of your face catches on the pillow every time you turn from one cheek to the other. A flat silk or cotton mask with a wide band stays where you put it.
