Best sleep mask for side sleepers: 3 picks that stay put without pressure
The best sleep masks for side sleepers — contoured cups vs flat silk, temple bulk, straps, and nose light leaks. Manta Pro, MZOO, and Alaska Bear compared honestly.

Short answer: Buy the Manta Pro if side sleeping has made every other mask shift or press on your eyes — its slim angled strap and C-shaped cups are built for it. The MZOO gets you most of the contoured, zero-eye-pressure benefit for a fraction of the price. If you hate foam and want the thinnest thing on your face, the Alaska Bear silk mask is flat and light, but it rests on your eyelids.
Quick picks
- Best overall for side sleepers
Manta Pro Sleep Mask — Slim angled strap, C-shaped adjustable cups, nothing touching your lids.
- Best value contoured mask
MZOO Contoured Sleep Mask — Deep memory-foam cups and thin curved sides at a budget price.
- Best flat silk mask
Alaska Bear Natural Silk Sleep Mask — 100% mulberry silk, buckle at the back of the head, packs flat.
Why most masks fail side sleepers
On your back, a mask only has to seal around your eyes. On your side, the pillow pushes the mask toward your nose or up your forehead, the strap presses into your temple, and a thick edge becomes a pressure point. The fixes are specific: thin or angled sides, a strap that lies flat (ideally with the adjuster at the back of the head, not over your ear), and cups or padding that don't lever off your face when one side is compressed.
Contoured cups vs flat silk
Contoured masks (Manta Pro, MZOO) hold fabric off your eyelids, so you can blink and there is no pressure on your eyes or lashes. The tradeoff is more structure at the side of your face. Flat silk masks (Alaska Bear) are the thinnest option and feel like almost nothing, but they lie directly on your lids and can slide if you press your face hard into the pillow. If eye pressure bothers you, go contoured. If bulk bothers you, go silk.
Our picks, with the tradeoffs
1. Best overall for side sleepers
Manta Pro Sleep Mask
The mask that converts people who 'can't wear masks.' Manta designed the Pro around side sleeping: a slim angled strap, C-shaped eye cups you can reposition, and ventilated materials. Expect a night or two of adjusting cup position and strap height to get it right.
Pros
- Slim angled strap and C-shaped cups designed for side sleeping
- Fully adjustable eye cups and head strap
- No fabric on your lids or lashes
- Ventilated, quick-drying materials
Cons
- Costs several times more than the other two
- Takes some fiddling to dial in cup and strap position
- Bulkier to pack than a flat mask
Best for: Dedicated side sleepers, lash-extension wearers, and anyone who has given up on cheaper masks.
Skip if: You want a cheap spare or hate adjusting things.
2. Best value contoured mask
MZOO Contoured Sleep Mask
Most of the contoured benefit for much less. MZOO's cups are deep, its sides are thinned and curved to reduce temple pressure, and the nose padding is generous. The catch is that the cups are fixed, so fit depends on your face.
Pros
- Deep contoured memory-foam cups (13 mm per the listing) — no eye pressure
- Thin, curved sides to reduce temple bulk
- Nose padding and bridge cutout to seal light
- Adjustable 19–28 in strap that won't snag hair
Cons
- Fixed cups — fit varies by face shape
- Memory foam can feel warm on hot nights
- Materials a step below Manta
Best for: Side sleepers who want contoured cups on a budget, or a travel spare.
Skip if: Fixed-cup masks haven't fit your face before.
3. Best flat silk mask
Alaska Bear Natural Silk Sleep Mask
The lightest option here: 100% mulberry silk with a raised nose cutout and a strap whose buckle sits at the back of your head, away from the pillow. Great if you hate foam; not the pick if you want zero contact with your eyelids.
Pros
- 100% mulberry silk — smooth and very light
- Adjustable 15.8–27.6 in strap; buckle sits at the back of the head
- Higher nose cutout to block light underneath
- Packs flat
Cons
- Rests on your eyelids — not for lash extensions or eye-pressure haters
- Can shift if you press your face hard into the pillow
Best for: Lighter side sleepers who dislike foam, and travelers.
Skip if: You need a mask that never touches your eyes.
How to choose
- Temple profile
- The side of the mask sits between your face and the pillow all night. Look for thin, tapered, or angled sides. A thick foam edge is the most common reason side sleepers give up on masks.
- Strap and adjuster placement
- An adjuster or buckle that lands over your ear becomes a pressure point. Prefer a strap that lies flat with the adjuster at the back of the head, and try wearing it slightly above the ears to stop the mask riding up.
- Cups vs flat
- Cups keep pressure off your eyes and lashes; flat silk is thinner. Pick based on which bothers you more: something touching your eyes, or bulk at the side of your face.
- The nose seal
- Most light leaks happen at the bridge of the nose, especially when the pillow shifts the mask. Look for real nose padding or a raised nose cutout.
- Fit is personal
- Face shape matters more than reviews. Buy from a listing with an easy return window and give a new mask three or four nights before judging it.
FAQ
What kind of sleep mask is best for side sleepers?
One with a low profile at the temples and a strap that lies flat. Contoured masks with thin, angled sides, like the Manta Pro or MZOO, keep pressure off your eyes; a flat silk mask like the Alaska Bear is the thinnest option but rests on your eyelids.
Why does my sleep mask move when I sleep on my side?
The pillow pushes the side of the mask toward your nose or up your forehead. A snug, adjustable strap worn slightly above the ears, thinner sides, and a mask that isn't tall at the temple all reduce shifting.
Is the Manta Pro worth it for side sleepers?
If cheaper masks keep pressing on your eyes or leaking light, yes — it's built around side-sleeping comfort with adjustable cups and a slim angled strap. It costs several times more than the MZOO, so try the MZOO first if budget matters.
Are silk sleep masks good for side sleepers?
They're the thinnest option and many side sleepers like them, but they lie directly on your eyelids and can shift. If eyelid pressure bothers you, choose a contoured mask instead.
Do contoured sleep masks block all light?
When the cups and nose padding fit your face, they seal very well, and both Manta and MZOO advertise 100% light blocking. Fit varies by face, so use the return window if light leaks at the nose.
