Slip Sleep Mask Alternatives: 5 Masks Compared Feature by Feature (2026)

The closest Slip sleep mask alternative is Blissy, which states the same 22-momme, grade-6A mulberry silk as Slip in a flat mask. Umisleep matches that spec and adds an adjustable strap. If you love the Contour for its lash-friendly shape, no other silk mask in our catalog copies it. Your choice is the Slip itself or a foam contour mask like MZOO.

Below, each alternative is matched to a reason people leave Slip: the silk, the strap, side sleeping or the shape. We compare shape, silk weight and grade, fill, strap and care. We also clear up two things most Slip reviews skip: Slip makes three different masks, and the Contour is foam inside a silk shell.

The short answer: the best Slip alternative for each reason you’re switching

• Same 22-momme, grade-6A silk in a flat mask: Blissy
• Same silk grade with an adjustable strap: Umisleep
• 22-momme silk with silk filling instead of foam, plus an adjustable strap: ZIMASILK
• Side sleeping with a wide, cushioned band: LitBear
• A contoured, lash-friendly shape, if you can give up silk: MZOO (memory foam, not silk)

Want silk and a contour in the same mask? Keep the Slip Contour. Nothing else in our catalog offers both.

First, which Slip are you replacing?

Slip sells three kinds of silk sleep mask: the classic flat Sleep Mask, the Contour and the Blockout. Each solves a different problem, so know which one you’re replacing before you pick a substitute.

The classic Sleep Mask

This is the flat slipsilk mask most people picture when they think of Slip. If it’s yours, the flat silk alternatives below (Blissy, Umisleep, ZIMASILK and LitBear) are the most direct swaps.

The Contour

According to Slip, its inner contour sits away from the eyelids to leave room for lashes, with eyelash extensions in mind. Two details are easy to miss:

• The silk is a shell. Slip says the mask is made with slipsilk excluding the elastic and piping, and the filling is PU foam.
• The strap is an elastic band that Slip doesn’t describe as adjustable.

Slip also says the Contour may not suit all lash lengths or types, and asks buyers to use their own judgement.

The Blockout

According to Slip, the Blockout is softly padded and made with 100% slipsilk (excluding the fastener). It closes with adjustable hook-and-loop fastenings.

The silk standard to match

Slip says slipsilk is 100% pure mulberry silk, grade 6A long fiber, at 22 momme. That is the benchmark for every alternative here. Slip also warns that some sellers make false momme claims, so treat every spec on this page, Slip’s included, as the brand’s own statement. Our guide to mulberry silk and momme explains what the numbers mean.

Side-by-side: Slip Contour vs. 5 alternatives

The comparison table on this page sets the Slip Contour against five alternatives on the features that actually differ: shape, material, silk weight and grade, fill, strap and care. Four patterns stand out:

• Silk weight is easy to match. Blissy, Umisleep, ZIMASILK and LitBear all state 22-momme mulberry silk, the same weight Slip gives for slipsilk.
• Grade is harder. Only Blissy and Umisleep state grade 6A. ZIMASILK and LitBear don’t list a grade.
• Shape is the real gap. Every silk alternative is flat. The only contoured option, MZOO, is memory foam and fabric, not silk.
• Straps vary the most. Fixed elastic, adjustable elastic, a wide hook-and-loop band or a buckle. The strap section below covers who each type suits.

Closest silk match: Blissy

If Slip’s silk is what you’re after, Blissy is the most like-for-like swap. The brand states 22-momme, grade-6A mulberry silk, the same weight and grade Slip gives for slipsilk, and the silk is OEKO-TEX certified. In a 2021 test of more than 15 masks, one blogger called the Blissy and Slip silk masks almost identical apart from the extras.

Blissy is flat, with a silk-covered elastic strap that doesn’t adjust. That makes it closest in spirit to Slip’s classic flat mask. It sits at the premium end, with polished finishing and packaging, and it blocks light well for a flat design.

Who it suits: anyone replacing Slip’s classic flat mask, and Contour owners who care more about the silk than the shape.

Who should skip it: lash-extension wearers, because without a contour the silk rests on your lashes. Skip it too if fixed straps never fit your head well.

Same silk spec, adjustable strap: Umisleep

Umisleep states the same silk spec as Slip, 22-momme, grade-6A mulberry, and adds what some Slip owners wish they had: an adjustable strap. Buyer comments on Slip.com and Cult Beauty describe the Contour’s band as an elastic they wish were adjustable, and one Cult Beauty buyer said it was a bit tight. If that’s why you’re leaving, Umisleep is the cleanest fix that keeps the silk spec.

The trade-offs: Umisleep is a newer brand with less of a track record than Slip or Blissy, and it offers fewer colors for now. Like Blissy, it’s flat, so it won’t keep silk off your lashes. Care is hand wash.

Who it suits: spec-focused buyers who want 6A, 22-momme silk with a fit they can adjust.

Who should skip it: anyone who wants an established brand name, a contoured shape or a wide choice of colors.

Plush 22-momme feel: ZIMASILK

The Slip Contour gets its cushion from PU foam under the silk. ZIMASILK pairs a 22-momme mulberry silk shell with silk filling, so the padding is silk rather than foam. The filling adds a soft cushion that also helps block light. According to the product details, the adjustable elastic strap fits most head sizes.

The trade-offs:

• A filled mask runs slightly warmer than an unfilled flat one.
• The filling can shift over time.
• The shape is flat, so the cushion rests on your eyelids instead of around them.
• ZIMASILK doesn’t state a silk grade.

Care is hand wash and air dry.

Who it suits: Contour owners who like a padded mask but want silk inside as well as out, and anyone who needs an adjustable strap.

Who should skip it: hot sleepers, who are better off with an unfilled mask, and lash-extension wearers.

For side sleepers: LitBear

LitBear keeps 22-momme mulberry silk but rethinks the strap. Instead of a thin elastic, it uses a wide cushioned band with hook-and-loop adjustment, which the brand designs for side sleepers. A nose pad is meant to reduce light leaks, and the mask is described as soft and breathable for warm sleepers.

Reports on the Contour for side sleeping are mixed. A Fashionista editor found it gave a firm cushion on her side, while one 2021 tester found it didn’t stay put through tossing and turning. If your mask ends up on the pillow by morning, a wide adjustable band is the more targeted fix.

What you give up: plainer styling than Slip’s, no contour and no stated silk grade. The hook-and-loop closure can also catch on hair. Choose it over Slip only if fit matters more to you than finish. For more options, see our guide to the best silk sleep masks for side sleepers.

Who it suits: side and stomach sleepers, and anyone whose mask keeps sliding off.

Who should skip it: people with long hair that tangles easily, and buyers who want Slip’s polished look.

If you want the Contour’s shape: MZOO (not silk)

If you bought the Contour for its shape, with lashes free and room to blink, here’s the honest answer: no silk mask in our catalog copies it. MZOO is the closest match on shape. According to the brand, its molded 3D eye cups put zero pressure on eyes and lashes, and they are deep enough for lash extensions and eye movement during REM sleep. MZOO also rates it for 100% light blocking. An adjustable buckle handles fit.

It is not silk. MZOO is contoured memory foam with a low-bounce fabric. It feels warmer against the skin and doesn’t offer the benefits people buy silk for. Our guides to the benefits of a silk sleep mask and silk vs. satin sleep masks explain what that difference means. It’s also bulkier to pack than a flat silk mask.

Slip’s lash caveat applies here too. Slip says the Contour may not suit every lash length or type, so check how much room MZOO’s cups leave for your own lashes.

Who it suits: lash-extension wearers and light-sensitive sleepers who care most about shape and blackout.

Who should skip it: anyone who chose Slip for the silk against their skin.

Straps and fit: the difference most reviews skip

Most Slip reviews focus on the silk. But the strap decides whether a mask stays on and stays comfortable. Here’s how the six compare:

• Slip Contour: elastic band. Slip doesn’t describe it as adjustable. Some buyers say it’s a bit tight or wish it adjusted, and one tester found it slid off with tossing and turning. Slip’s Blockout, by contrast, has adjustable hook-and-loop closures.
• Blissy: fixed silk-covered elastic. Smooth and simple, but not adjustable, so the fit is what it is.
• Umisleep and ZIMASILK: adjustable straps. Tighten or loosen them to suit your head.
• LitBear: wide cushioned band with hook-and-loop. Adjustable and designed for side sleepers, but the closure can catch on hair.
• MZOO: adjustable buckle. Adjustable fit on a foam contour mask.

Which strap suits you

• Average head, happy with Slip’s fit: a fixed elastic like Blissy’s is the simplest swap.
• Smaller or larger head, or a band that feels tight: choose an adjustable strap (Umisleep, ZIMASILK, LitBear or MZOO).
• Long or thick hair: hook-and-loop can snag, so an adjustable elastic strap is the easier option.
• Restless sleepers and side sleepers: an adjustable strap helps keep the mask in place, and LitBear’s wide band is the one its brand designs for side sleeping.

Washing: Slip vs. the alternatives

Every Slip mask is hand-wash only, and the rules are strict:

• Wash the classic and Blockout masks in cold water.
• Wash the Contour at 30–40°C (86–104°F).
• Never put any Slip mask in the washing machine.
• Air-dry in the shade, and don’t use a tumble dryer.

Most alternatives work the same way. Umisleep, LitBear and MZOO are listed as hand wash, and ZIMASILK as hand wash and air dry. Blissy is the exception: the brand says machine washing is allowed, though hand washing is gentler on silk.

When to just buy the Slip

Sometimes the best alternative is no alternative. The Slip Contour is still the right buy if:

• You want silk and a contour in one mask. It is the only mask in our catalog that is both. The shell is slipsilk, and the inner contour is designed to sit away from your eyelids.
• You’re buying a gift. Slip is the luxury name many recipients already know. Our silk sleep mask gift guide has more ideas.
• The elastic band fits you. If it doesn’t feel tight and the mask stays on through the night, the strap complaint some buyers raise doesn’t apply to you.

Go in knowing the details. The padding is PU foam, Slip doesn’t describe the band as adjustable, and the mask is hand-wash only. Slip also says it may not suit every lash length, and the contoured shape is bulkier for travel. Every model on this page has its own write-up in our reviews.
