Manta Sleep
Manta PRO Sleep Mask

Trade-off: Bulk and price: it is the largest and dearest mask in our catalogue.
Head-to-head
Manta PRO vs Nidra: the fullest seal or the slimmest profile?
Two contoured masks built to opposite priorities: the Manta PRO to seal every face, the Nidra to stay comfortable on a pillow.
The short answer
Side sleepers who have abandoned bulky masks should buy the Nidra: deep cups inside, slim edge outside, light enough to forget. Everyone else chasing the most complete blackout should buy the Manta PRO, whose movable cups seal faces a fixed shape cannot. The Nidra gives up some seal for comfort on the pillow; the Manta gives up comfort on the pillow for seal. Decide which failure you have had before.
Nidra
Nidra Contoured Deep-Rest Sleep Mask
Best for: Side sleepers who want a contoured mask they can forget about.
Trade-off: The slimmer edge gives up some seal at the nose compared with deeper masks.

When each one wins
Choose by your situation, not by the spec sheet
Choose the Manta PRO if…
- Total darkness is the goal and you sleep on your back or lightly on your side.
- Fixed cups have never fitted your face.
- You want machine washing.
Choose the Nidra Deep-Rest if…
- You sleep on your side and deep masks lever off the pillow.
- You want the lightest contoured mask you can forget on a flight.
- You have a narrow face and want a Small size.
Neither makes sense if…
- You sleep face-down — a flat mask.
- You share a room and would rather darken it with curtains.
The SleepOriginal verdict
Manta PRO or Nidra Deep-Rest?
These masks answer different complaints. "Light gets in" is the Manta PRO's problem to solve; "it digs into the pillow" is the Nidra's. Buy for the complaint you actually have, and if you have both, the Nidra plus a well-hung curtain is a better pair than either mask alone.
Questions
Manta PRO vs Nidra Deep-Rest FAQ
Can the Manta PRO be worn on the side?
Yes, and Manta markets it that way, but its cups are deeper than the Nidra's and you will feel them against the pillow. Committed side sleepers usually prefer the Nidra.
