Best Overall Value
Our top pick for most sleepers
Silk Pillowcase with Zipper & Laundry Bag
- Hidden zipper closure
- Free silk laundry bag included
- Hypoallergenic
- Temperature regulating
- Anti-aging benefits
The Promeed Silk Pillowcase is the clear winner in our testing. At just $29 (down from $49), it delivers 23-momme, 6A+ grade mulberry silk that outperforms pillowcases costing two to three times as much. The hidden zipper closure keeps the pillow securely in place, and the included silk laundry bag is a thoughtful touch that extends the life of your investment.
In our sleep tests, we noticed noticeably less friction on both skin and hair compared to cotton and satin alternatives. The temperature regulation was excellent, staying cool on warm nights without feeling clammy. Available in five neutral colors, it fits seamlessly into any bedroom aesthetic.
Who it's for: Anyone who wants premium silk quality without the premium price tag. Especially great for first-time silk buyers.
Most Color Options
Blissy
Blissy has become a household name thanks to aggressive marketing and celebrity endorsements. The pillowcase itself is solid: 22-momme, 6A grade silk with OEKO-TEX certification. With 44+ color options, it wins on variety. However, at $76, you're paying a significant premium for the brand name. The 60-night return policy is generous and a point in its favor. We found the silk quality comparable to other 22mm options, but it doesn't quite match the 23mm density of our top pick.
Best Brand Recognition
Slip
Slip is the OG luxury silk pillowcase, endorsed by dermatologists and celebrities alike. At $89, it's the most expensive option in our roundup. The 22-momme silk feels luxurious, but in blind testing our panel couldn't consistently distinguish it from less expensive 22mm options. If brand prestige matters to you, Slip delivers. For pure value, though, there are better options available.
Best Budget Alternative
Lilysilk
Lilysilk offers a solid mid-range option at $48. The 22-momme, 6A grade silk is OEKO-TEX certified and performs well in our tests. The envelope closure is functional but less secure than a zipper design. With 20+ colors and a reasonable price point, it's a good choice for shoppers who want something nicer than budget silk without paying luxury prices.
Silk Pillowcase Buying Guide
Momme Weight
Momme (mm) measures silk density. For pillowcases, look for 19mm or higher. We recommend 22-25mm for the best balance of durability, softness, and luxury feel. Our top pick uses 23mm, which we consider the sweet spot. Learn more about momme count.
Silk Grade
Silk is graded from A to 6A (highest). Grade 6A silk uses the longest, most uniform fibers, resulting in a smoother, more durable fabric. Look for 6A or 6A+ grade for pillowcases you'll use nightly.
Closure Type
Zipper closures keep your pillow fully enclosed and secure. Envelope closures are simpler but can slide open during the night. We prefer hidden zippers for a clean look and better function.
Certifications
OEKO-TEX certification means the silk has been tested for harmful substances. This is especially important since a pillowcase sits against your face for 8 hours a night.
Frequently Asked Questions
Are silk pillowcases really worth it?
Yes. Silk creates significantly less friction than cotton, which means less tugging on your skin and hair while you sleep. Over time, this can reduce sleep creases, minimize hair breakage, and help your skin retain moisture. The benefits are backed by dermatologists and our own testing.
How do I wash a silk pillowcase?
Most silk pillowcases can be machine washed on a delicate/cold cycle inside a silk laundry bag. Use a gentle, pH-neutral detergent. Avoid bleach and fabric softener. Air dry or tumble dry on the lowest setting. Some brands, like Promeed, include a laundry bag for easy care.
How long do silk pillowcases last?
With proper care, a high-quality silk pillowcase (22mm+) can last 2-5 years. Higher momme weights tend to be more durable. Replacing your pillowcase every 1-2 years is ideal for hygiene, similar to any bedding.
What's the difference between silk and satin pillowcases?
Silk is a natural fiber with inherent benefits like moisture retention, temperature regulation, and hypoallergenic properties. Satin is a weave pattern that can be made from polyester or other synthetics. While satin is smoother than cotton, it doesn't offer the same skin and hair benefits as real mulberry silk.
Is a higher momme count always better?
Not always. While higher momme means denser, more durable silk, extremely high momme counts (30+) can feel heavy. For pillowcases, the 22-25mm range is ideal. We find 23mm to be the sweet spot for softness, durability, and breathability.
