Umisleep 22 Momme 6A Mulberry Silk Sleep Mask

Quick verdict

Umisleep is the fastest-rising mask on this list and the clearest spec-value play in the premium material tier. It offers 22-momme, grade-6A mulberry silk — the same headline specification as the Blissy, which costs significantly more — at a mid-tier price. The trade-off is track record: Umisleep is newer, has fewer verified long-term user cycles to draw on, and offers fewer color options. If you’re spec-driven and comfortable with a newer brand, the value is real.

Our take

Umisleep’s pitch is simple: it claims premium silk specs at a price that undercuts established premium brands substantially. On paper the spec is genuinely premium: 22-momme silk is denser than the 19-momme silk used by most budget masks, and grade 6A is the top of the commercial grading scale — though, as with every brand, that grade is self-reported rather than independently certified.

On materials, the Umisleep is close to the Blissy: both use 22-momme, grade 6A mulberry silk, which is dense, smooth and cool against the skin. The difference is construction and price. The Blissy finishes its strap more carefully; the Umisleep uses a standard adjustable strap and sits a price tier lower. For the core experience of 22-momme silk on your face, the two are close.

Light blocking is flat-mask standard — better than the typical 19-momme flat mask due to the denser weave, but not at the level of a filled or contoured option. The strap is a soft adjustable band rather than Blissy’s silk-wrapped design, so the fit is easy to fine-tune even if the finish is simpler.

The main uncertainty with Umisleep is longevity. Established brands like Alaska Bear and Blissy have multi-year track records behind their durability claims; Umisleep, as a newer arrival, doesn’t yet. The 22-momme spec suggests it should hold up, but that’s an inference from the material rather than a documented track record.

How it compares

Against the Blissy (22-momme, 6A, flat): Direct competitors. Blissy wins on brand track record, silk-wrapped strap, and packaging quality. Umisleep wins on price for the same material specification. If track record matters to you, pay the Blissy premium. If you’re comfortable with a newer brand offering the same spec, Umisleep is the value choice.

Against the ZIMASILK (22-momme, filled): ZIMASILK adds a silk filling for more cushion and better light blocking. Umisleep is flat. Choose ZIMASILK if you want cushion; choose Umisleep if you want a flat 22-momme option at a lower price than Blissy.

Against the Alaska Bear (19-momme, flat): Alaska Bear is significantly cheaper with a slightly lighter material. For everyday use, either works; for maximum longevity and slightly better opacity, the 22-momme Umisleep is worth the step up.

Who this is for

• Spec-driven buyers who want grade-6A, 22-momme silk without paying the premium brand premium
• Anyone curious about a newer challenger in the premium silk space
• People who have used the Alaska Bear for a while and want a meaningful material upgrade

Who should skip it

• Anyone who needs a brand with a multi-year durability track record — choose Blissy or Slip
• Lash extension wearers who need eye clearance — this is a flat mask; choose Slip Contour
• People with a strong preference for specific colors — Umisleep’s range is currently limited

Care and durability

Hand wash in cool water with a gentle silk detergent. Air dry flat. The 22-momme silk is inherently more durable than 19-momme alternatives, but Umisleep has less of a public track record than older premium brands, so there’s less to go on about how it ages. Handle with the same care as any premium silk: no machine washing, no wringing.
