Is Sillo Worth It vs Blissy and Slip?
Silk pillowcases range from $20 to over $200. That range is not random. It reflects real differences in material specification, manufacturing quality, what is actually included in the box, and how much of the price tag goes toward the product versus the brand's marketing budget. Once you understand the two or three numbers that actually determine quality, the comparison becomes very straightforward.
This is an honest breakdown. We make Sillo, so we have a point of view, but we will show you exactly how to evaluate any silk pillowcase on the market using the same criteria we hold ourselves to.
The Specifications That Actually Determine Quality
Two numbers determine whether a silk pillowcase is genuinely premium or just marketed that way.
Momme Weight
Momme weight is the density of the silk weave. The higher the number, the more silk is packed into the fabric. For pillowcases, 19 to 22 Momme is the functional range. Below 19 Momme, the silk is thinner, degrades faster through repeated washing, and provides a less consistent friction-reduction benefit over time. Above 22 Momme for a pillowcase, you are paying for weight that does not meaningfully improve the experience in this application.
22 Momme is the industry benchmark. It is what Sillo, Blissy, and Slip all use. If a brand does not list their momme weight, that is worth noting.
Silk Grade
Silk grade runs from A (lowest) to 6A (highest) and describes the quality and consistency of the raw silk filament before weaving. Grade 6A silk comes from the finest, most uniform part of the silkworm cocoon. Lower grades have more variation in the filament, which creates subtle inconsistencies in surface smoothness over the life of the pillowcase.
22 Momme and Grade 6A together are the benchmark for premium. If a brand discloses both and you can verify it, the material specification is there. If they only disclose one or neither, you are buying on brand trust alone.
What the Specifications Do Not Tell You
Momme and grade describe the raw material. They do not describe what has been added to the fabric during production. This is where Sillo separates from every other brand in the comparison.
What Makes Sillo Different: Silver Ion Technology
Sillo pillowcases are infused with silver ions integrated into the silk fibre during the weaving process. This is not a coating or a surface treatment applied after the fact. The silver ions become part of the fabric structure itself, which means the antimicrobial properties do not wash out over time.
Silver has a well-established history in medical and skincare applications for its ability to inhibit bacterial growth. On a pillowcase, this matters for one specific reason: your face is in contact with that surface for six to eight hours every night.
Even with regular washing, your pillowcase accumulates bacteria, skin oils, and product residue between washes. Silver ion technology creates an environment that actively works against that buildup while you sleep.
Neither Blissy nor Slip offers silver ion technology. At equivalent momme weight and grade, this is the single biggest functional difference between Sillo and the alternatives.
Dermatologist Reviewed
Sillo's silk pillowcases have been reviewed and endorsed by Dr. Jessica Burgy MD, a Board Certified Dermatologist and Science-based Skincare Expert. Her assessment:
"I have really enjoyed using Sillo silk pillowcases. They stay cool through the night, feel gentle on my skin, and I have noticed less frizz in my hair in the morning. The quality and overall experience have been excellent, and I would absolutely recommend them as part of a thoughtful hair and skin care routine."
This is not a paid influencer promotion. Dr. Burgy is a board-certified dermatologist evaluating Sillo on clinical grounds: skin contact, friction reduction, material quality, and practical experience with the product. Neither Blissy nor Slip carries equivalent third-party dermatologist endorsement. When you are buying a pillowcase specifically for skin or hair health reasons, that distinction matters.
What Comes in the Sillo Gift Set
This is often the part of the comparison that gets overlooked. Most silk pillowcase brands sell a single pillowcase or a basic set and leave it at that. The Sillo gift set is built differently.
Every Sillo purchase includes:
•      Two 22 Momme Grade 6A Silver Ion Silk Pillowcases (Queen or King size)
•      Sillo Care Washbag included with every set, a fine-mesh delicate laundry bag designed specifically to protect silk through every machine wash
Â
The Care Washbag matters more than it sounds. The AAD recommends washing pillowcases one to two times per week for skin health. Without a protective mesh bag, machine washing silk accelerates fabric degradation. The Washbag is not an accessory, it is the tool that makes the skin and hair benefits of the pillowcase sustainable over years, not months. You can also use it to protect other delicates like lingerie and bras.
Neither Blissy nor Slip includes anything equivalent. Their purchase is a pillowcase. Sillo's purchase is a complete silk care system.
Price Comparison
•      Sillo Queen 2-Pack (2 pillowcases + Care Washbag): $99.99 USD
•      Sillo King 2-Pack (2 pillowcases + Care Washbag): $109.99 USD
•      Blissy Queen (single pillowcase): approximately $105.95 USD
•      Slip Queen (single pillowcase): approximately $120 to $125 USD
Â
To get two pillowcases from Blissy or Slip, you are spending between $210 and $250 USD with nothing included for care or washing. Sillo's 2-pack delivers the same material specification at approximately $50 USD per pillowcase, with the Care Washbag included, silver ion technology included, and dermatologist endorsement behind the product.

Why the 2-Pack Changes the Value Calculation
Washing cadence is the part of the silk pillowcase conversation that most brands skip past because it is inconvenient for their pricing model. For skin health, you need to wash your pillowcase one to two times per week. A single pillowcase means a regular gap while it washes and air dries, typically six to twelve hours. During that time you either use an unwashed pillowcase or skip the routine.
Two pillowcases solves this completely. One washes while you use the other. You never have to compromise the hygiene cycle that makes the silk pillowcase genuinely worthwhile.
The 2-pack is not a discount mechanism. It is the correct way to own a silk pillowcase for skin and hair health purposes. Sillo's pricing is built around that from the start.
Frequently Asked Questions
Is Sillo actually 22 Momme and Grade 6A?
Yes. Both specifications are stated on every product listing and on the packaging. Certification documentation is available through Sillo's customer team for anyone who wants verification.
Does Slip justify its price over Sillo?
Slip offers genuine 22 Momme silk with a wide colour range and strong brand recognition. At approximately double the per-pillowcase cost of Sillo, without silver ion technology, without a Care Washbag, and without third-party dermatologist endorsement, the product specification does not justify the price premium. You are paying for the brand name, not a better product.
Is Sillo dermatologist approved?
Yes. Dr. Jessica Burgy MD, a Board Certified Dermatologist, has reviewed and endorsed Sillo silk pillowcases based on their material quality, skin contact performance, and real-world experience with the product.
What is in the Sillo gift set exactly?
Every Sillo set includes two 22 Momme Grade 6A Silver Ion Mulberry Silk Pillowcases and one Sillo Care Washbag. The Sillo Care Washbag is a fine-mesh delicate laundry bag designed to protect silk pillowcases and other delicates through every machine wash.
What about Amazon generic "22 Momme" pillowcases for $30?
Momme weight claims on unbranded Amazon listings are not reliably verified. Genuine 22 Momme, Grade 6A production economics make the $30 price point implausible. Treat undisclosed-grade, very low-priced silk claims with appropriate scepticism.
Does Sillo ship to Canada?
Yes. Sillo ships to Canada with CAD pricing. The Queen 2-pack is $129.99 CAD and the King 2-pack is $149.99 CAD, both including the Care Washbag.
The Wrap Up!
The premium silk pillowcase category has clear quality benchmarks: 22 Momme, Grade 6A, Mulberry Silk. At those specifications, the per-pillowcase cost difference between brands reflects brand investment rather than product quality. Sillo matches those specifications and goes further with silver ion technology integrated into the fibre, a Care Washbag included in every set, and endorsement from a Board Certified Dermatologist.
For a product you use every night for three to five years, those differences are worth understanding clearly.
Two 22 Momme, Grade 6A, silver-infused silk pillowcases plus a Care Washbag for $99.99 USD. See the full Sillo set here.
