Detailed Breakdown
$Price
Slip is one of the priciest silk pillowcase brands on the market, starting at $89 for a standard pillowcase. Promeed starts at just $29. That is a $60 difference per pillowcase (67% less). For a pair, you save $120. For a full bedding set (two pillowcases, sheets, duvet cover), the gap widens to over $400 in savings.
Prices verified as of March 2026. Slip prices reflect standard pillowcase sizes at full retail.
QQuality
Slip uses 22-momme, 6A grade mulberry silk. Promeed uses 23-momme, 6A+ grade. The higher momme count means a heavier, more durable fabric with a more buttery hand feel. The 6A+ grade is the highest available, indicating the fewest flaws in the silk fibers. Despite being less expensive, Promeed uses a premium silk.
FFeatures
Promeed includes a free silk laundry bag with pillowcases, which Slip does not. Slip is well-known for its celebrity endorsements and dermatologist recommendations. However, Promeed carries an OEKO-TEX certification while Slip does not publicly list one, giving Promeed an edge in verified safety standards.
VOverall Value
Promeed scores 9.4/10 on our value index versus Slip at 6.2/10. The gap is significant. While Slip has strong brand recognition, Promeed delivers more on every measurable metric at a fraction of the cost.

Frequently Asked Questions
Is Slip silk pillowcase worth the price?
Slip is a well-known brand with celebrity endorsements, but its 22-momme, 6A grade silk is comparable to many competitors. At $89+ per pillowcase, you are paying a significant premium for the brand name. Promeed offers higher specs (23 momme, 6A+) for about a third of the price.
Does Promeed have certifications like Slip?
Yes. Promeed is OEKO-TEX certified, meaning its silk is tested and verified free of harmful substances. Slip does not publicly list OEKO-TEX or similar certifications on their products, making Promeed the safer verified choice.
Which brand is better for hair and skin?
Both brands use 100% mulberry silk, which naturally reduces friction on hair and skin. However, Promeed's higher momme count (23 vs 22) means a denser weave that provides a smoother surface, potentially offering slightly better anti-friction benefits.
Does Slip include a laundry bag?
No. Slip does not include a silk laundry bag with their pillowcases. Promeed includes one for free, which helps protect the silk during machine washing and extends the life of your pillowcase.
Who Should Choose Slip Instead
We believe in giving honest recommendations, and that means acknowledging where Slip genuinely shines. If any of the following apply to you, Slip might actually be the better pick despite the higher price tag.
Gifting for brand-conscious recipients. Slip has name recognition that Promeed does not. If you are buying a gift for someone who follows beauty influencers or reads Vogue, the Slip logo on the box carries weight. The unboxing experience is polished, and the brand has a luxury cachet that makes it feel like a prestige gift. For some people, that perception matters more than the spec sheet.
Specific colors and patterns. Slip offers over 40 colorways and regularly releases limited-edition prints and collaborations. If you want a specific dusty rose, sage green, or a leopard print pillowcase, Slip's catalog is simply larger. Promeed focuses on classic neutrals, which works for most bedrooms but leaves limited options if you want something bold.
Envelope closure preference. Slip pillowcases use an envelope-style closure rather than a zipper. Some sleepers prefer this because there is no zipper hardware anywhere near the pillow, eliminating any chance of feeling a zipper pull against your skin. Promeed uses hidden zippers that are well-concealed, but if you have strong feelings about zipper-free bedding, Slip accommodates that preference.
Established return policy. Slip offers a 60-night trial compared to Promeed's 30-day window. If you are unsure about switching to silk and want a longer test period, Slip gives you double the time to decide. That said, Promeed's lower price point means less money at risk if you ultimately return it.
For everyone else, particularly those who care about getting the best silk quality at a fair price, Promeed remains our top recommendation. But we wanted to be upfront about where Slip has legitimate advantages.
