Manta Sleep Mask
The Manta Sleep Mask is the gold standard for circadian optimization due to its guaranteed 100% blackout capability and modular design. By eliminating all light leaks, it prevents the suppression of melatonin, even in bright environments.
Ingredients & Purity
Constructed with OEKO-TEX certified fabrics; the eye cups are made of breathable modal and the strap is a snag-free industrial-grade hook and loop.
Scientific Evidence
While masks themselves aren't drugs, the physiological impact of 100% darkness on the pineal gland's melatonin production is well-documented in circadian biology.
Brand Transparency
Manta provides detailed material breakdowns and clear manufacturing origins, maintaining high standards for textile safety.
Value Assessment
At $35, it is priced mid-range but offers significantly higher durability and customization than budget silk masks.
Why Not Alternatives?
Unlike flat masks (like Slip or Alaska Bear), Manta uses adjustable eye cups that create a true seal around the eyes without applying pressure to the eyelids, preventing the 'blurred vision' effect and ensuring total darkness for all face shapes.
