Manta Sleep Mask Pro vs Slip Pure Silk Sleep Mask

Which is the better buy? Side-by-side on rating, price, strengths, and watch-outs — with the published ratings we averaged to get there.

The short answer

Manta Sleep Mask Pro comes out ahead by a narrow margin (4.7 vs 4.6). The gap is mostly about Side sleepers, eyelash-extension wearers, shift workers, and frequent flyers who want true 100% blackout without any pressure on the eyes — read the strengths below before deciding.

Higher ratedRanked #1 in Best Sleep Masks

Manta Sleep Mask Pro

4.7

$85

The Manta Pro is the contoured blackout mask Manta engineered specifically for side sleepers and people with eyelash extensions. C-shaped foam cups create a no-touch buffer around the eyes while sitting flat against the temples, and the perforated foam strap stays put without pressing into the side of the head. Reviewers across Sleep Foundation, BSB Insider and travel blogs consistently call it the gold standard for true blackout, though at $85 it asks a premium most casual sleepers will not need to pay.

Strengths

— C-shaped eye cups deliver true 100% blackout with zero pressure on eyelids or lashes
— Eye cups sit flat at the temples so the mask stays put for side sleepers
— Perforated foam strap and Tactel interior keep the face cool through long wear

Watch-outs

— At $85 it is one of the most expensive non-tech sleep masks on the market
— Bulkier than flat silk masks and packs larger in a carry-on
— Some testers report forehead indents after a full night of wear

Ranked #2 in Best Sleep Masks

Slip Pure Silk Sleep Mask

4.6

$72

Slip helped invent the silk pillowcase category, and the Pure Silk Sleep Mask is its sleep accessory in the same idiom. It is the heaviest silk in the category at 22 momme, with pure silk filler and internal liner that give the mask actual structure rather than the floppy satin feel of cheaper options. The mask is gentle on skin and lashes and won the 2018 Selfridges Beauty Award, but it is flat-fronted and will leak light at the nose bridge for anyone who needs true blackout.

Strengths

— Highest-grade 22 momme mulberry silk on both sides feels smooth on skin and hair
— Pure silk filler and internal liner give it more body than thinner satin masks
— Silk-covered elastic band does not crease or pull at hair through the night

Watch-outs

— Flat design leaks light at the nose bridge and outer cheekbones
— Eyelids can still feel mild pressure during long-wear sessions
— $72 price tag is high for what amounts to a luxe basic

How they stack up

Manta Sleep Mask Pro

Splits the field with the Alaska Bear Natural Silk Sleep Mask: both use contoured cups to keep fabric off the eyelids, but the Manta Pro is engineered around side sleepers where the Alaska Bear's foam insert is thinner and more travel-friendly. Heavier and bulkier than the Slip Pure Silk Sleep Mask, but Slip leaks light at the nose bridge that the Manta Pro fully seals.

Slip Pure Silk Sleep Mask

Sits in a different lane than the Manta Sleep Mask Pro: Slip is a flat silk mask built around skin and hair care, where the Manta Pro is engineered for true blackout. Heavier and more luxurious silk than the Alaska Bear Natural Silk Sleep Mask, but Alaska Bear is contoured where Slip is flat. Skin-friendlier than the Tempur-Pedic Sleep Mask but blocks less light at the nose.
