Deep dive
Manta's design gives total blackout — you can open your eyes inside the mask and see nothing. The hollow eye cups create a seal that no contour mask can match. Alaska Bear is very good (95%+ blackout) but not total — thin light strips can leak around the nose.
For light sleepers who wake at any dawn light, Manta's difference is worth the premium. For occasional use, Alaska Bear's blackout is plenty.
Manta's key innovation: hollow eye cups. Your eyelids never touch anything. No pressure = no waking up to remove the mask. Alaska Bear's contour design touches your eyelids gently but does touch — some sleepers report eye pressure over long-term use.
Manta is the only mask most reviewers actually keep on all night. Alaska Bear ends up on the nightstand for many.

Where to buy

For daily use, Manta — the adjustable cups solve the eye-pressure problem that any silk contour mask has. For travel or occasional use, Alaska Bear, at about a quarter of the price.
Yes — velcro straps hold them well. Manta ships extra cups if you lose one. The design has held up across 3 million+ users over 5+ years.
Yes — 22-momme mulberry silk (the gold standard). Not silk blend. Cheaper than Manta because the design is simpler (no cups, no engineering).
Manta by a wide margin. The eye cups stay positioned under pillow pressure. Alaska Bear can shift out of place on a pillow.
Manta has 1" clearance inside the eye cups — contact lens wearers can nap without removing lenses. Alaska Bear contours to your eyelids — remove contacts before wearing.
Alaska Bear is better for travel — lighter, packs smaller, cheaper if lost. Manta is fine for travel but overkill unless you fly regularly.
