Cheap masks leak light and shift at night — Manta's contoured cups create a total blackout seal.
Why Not Just Buy the Cheap One?
Standard foam or silk masks flatten against your eyes, letting light in through gaps. Manta's adjustable, concave eye cups mold to your face with zero pressure on your eyelashes. No light, no headaches.
The Buy-Once Math
A $10 drugstore mask lasts a few months before the elastic stretches. That's $20+ a year for constant frustration. For $35, this mask stops the leak and lasts years — best sleep investment you'll make.
