Slip Pillowcase Canada: What It Is, Where to Buy It, and Whether It Is Worth It

What Is Slip and Why Is It Popular in Canada?

Slip is an Australian brand that became widely known through beauty and wellness communities for its silk pillowcases. The brand's core claim is that sleeping on silk reduces hair breakage, minimises sleep creases on the face, and feels more comfortable than cotton for people with sensitive skin. Their products are positioned in the premium segment of the bedding market, and they are now available to Canadian shoppers through several retail channels.

The Slip pillowcase has become particularly associated with skincare and hair care communities, where it is often recommended alongside silk bonnets and hair wraps as part of a protective nighttime routine. For people with chemically treated hair, curly hair prone to frizz, or skin prone to irritation from rough fabrics, the argument for a silk pillowcase has a practical basis.

This guide covers what Slip pillowcases are made of, where to buy them in Canada, how to care for them, and whether the price is justified for your specific needs.

Slip Pillowcase Specifications

The 22 momme silk weight is worth understanding. Momme (mm) is a unit of silk weight equivalent to grams per square metre in heavier fabrics. A 22 momme silk is substantially heavier and more durable than the 12 to 16 momme silk used in budget silk products. Heavier silk holds its structure better over time, washes more reliably, and feels more substantial against the skin.

Where to Buy Slip Pillowcases in Canada

Canadian shoppers have several options for purchasing Slip products, each with different trade-offs on price, availability, and return policies.

Retailer	Channel	Notes
Slip (slipsilkpillowcase.com)	Online, ships to Canada	Full range of colours and sizes; shipping costs apply
Sephora Canada	Online and in-store	Select colours; easier returns; Beauty Insider points
Nordstrom Canada	Online	Good return policy; ships to most provinces
Well.ca	Online	Canadian retailer; free shipping on qualifying orders
Amazon.ca	Online	Verify seller is authorized; some third-party listings are counterfeit

The Amazon.ca note is important. Slip has been widely counterfeited, and lower-grade silk or polyester satin pillowcases have been listed under names designed to look similar to the Slip brand. When buying through Amazon, ensure the seller is either Slip directly or an authorized Canadian retailer. Buying from Sephora Canada or the Slip website directly eliminates this risk.

The Difference Between Silk and Satin Pillowcases

These two materials are frequently confused. Understanding the difference helps clarify why Slip commands the price it does compared to cheaper alternatives marketed as silk or satin.

Feature	Silk (mulberry)	Satin (polyester)
Material origin	Natural protein fibre from silkworms	Synthetic polymer (plastic)
Feel	Smooth, temperature-regulating	Smooth but can feel warm and sticky
Breathability	Highly breathable	Low breathability
Friction reduction	Very low friction	Low friction
Price range (CAD)	$70 to $200+	$10 to $40
Durability	High with proper care	Moderate; can snag and pill
Skin and hair benefit	Yes, due to natural properties	Partial (friction reduction only)

Satin pillowcases made from polyester do reduce friction against hair and skin compared to woven cotton. This is a genuine benefit that comes at a low cost. However, polyester satin does not breathe the way silk does, which means it can feel warm and sweaty during sleep. For hot sleepers, a polyester satin pillowcase may be uncomfortable even if it reduces hair friction.

Silk naturally regulates temperature because it is a protein fibre with a structure that moves moisture away from the body. This is the property that satin cannot replicate and the reason genuine silk commands a premium. Our article on the difference between silk and satin pillowcases covers this in more detail.

Benefits of a Silk Pillowcase: What the Evidence Says

The claims around silk pillowcases range from scientifically supported to anecdotal. Here is an honest assessment of what is known.

Hair breakage and frizz reduction: Cotton pillowcases have a woven texture that creates friction as hair moves across the surface during sleep. This friction causes cuticle damage over time, leading to split ends, breakage, and frizz. Silk's smooth surface generates significantly less friction. This is well supported by the physical properties of the materials, and many hair stylists recommend silk or satin pillowcases for chemically treated or naturally curly hair.

Skin crease reduction: Sleep creases occur when skin is pushed against a surface repeatedly through the night. A smoother pillowcase reduces the degree of skin folding. Whether this translates to fewer permanent wrinkles over time is less clearly established, though dermatologists frequently recommend silk pillowcases as part of an anti-ageing skincare routine.

Moisture retention for skin: Cotton absorbs moisture from skin during sleep, which can increase dryness. Silk absorbs less moisture, leaving more of the water and product you apply at night on your skin. For people using expensive serums or moisturisers, this is a practical argument for silk.

Hypoallergenic properties: Silk naturally resists dust mites and mould better than cotton. For people with allergies or asthma, this is a minor benefit, though regular washing matters more than pillowcase material for dust mite control.

How to Care for a Slip Silk Pillowcase

Silk requires more careful laundering than cotton or synthetic materials. Treating a Slip pillowcase incorrectly will shorten its life significantly.

1. Hand wash: Fill a basin with cool water and add a small amount of silk-safe detergent (look for pH-neutral or specifically silk-labelled formulas). Submerge the pillowcase and gently agitate for 2 to 3 minutes. Do not scrub or twist.
2. Rinse: Drain and refill with cool water. Gently press the pillowcase through the water to remove detergent. Repeat until water runs clear.
3. Remove excess water: Do not wring. Lay the pillowcase flat on a clean dry towel, roll the towel up with the pillowcase inside, and gently press to absorb water.
4. Dry: Unroll and lay the pillowcase flat on a dry surface away from direct sunlight. Do not tumble dry.
5. Iron if needed: Use the coolest setting on your iron and iron while slightly damp, or use a cloth between the iron and the silk.

If you choose to machine wash, use a mesh laundry bag, select the most delicate cycle available, and use cold water. Remove immediately when the cycle ends. This is not what Slip recommends, but it is what many users do in practice without visible damage to the pillowcase.

Is the Slip Pillowcase Worth It in Canada?

At $95 to $135 CAD for a single pillowcase, Slip is a meaningful purchase. Whether it is worth it depends on your specific situation.

The case for buying Slip: If you have chemically treated hair, naturally curly or coily hair, or skin that is prone to dryness or sensitivity, a genuine 22 momme silk pillowcase provides real and measurable benefits. If you are already spending money on hair treatments or skincare products that get absorbed by a cotton pillowcase at night, a silk pillowcase protects that investment.

The case against: If your hair is in good condition and your skin is not particularly sensitive, the benefit may not be noticeable enough to justify the cost. A polyester satin pillowcase at $15 to $30 CAD provides the friction-reduction benefit at a fraction of the price.

The middle ground: Some Canadian brands and retailers offer genuine mulberry silk pillowcases at a lower price point than Slip. Checking reviews carefully for momme weight and OEKO-TEX certification helps identify legitimate lower-cost silk options.

Silk Pillowcase Sizing: What Fits Your Pillow

Choosing the right Slip size ensures the pillowcase fits properly and the zipper closure lays flat without distorting the fabric.

Slip Size	Dimensions	Fits
Standard	20 x 26 inches (51 x 66 cm)	Standard pillows
Queen	20 x 30 inches (51 x 76 cm)	Queen pillows
King	20 x 36 inches (51 x 91 cm)	King pillows

If you are unsure which size your pillow is, measure it. A pillow that is too small for its pillowcase will slide inside and bunch up. A pillow that is too large for its case will stretch the fabric at the seams. For most Canadian bed setups, a standard-size pillow uses a standard-size pillowcase, and queen-size pillows are used on queen beds.

Protecting Your Sleep Investment Beyond the Pillowcase

A silk pillowcase is one component of a sleep environment. The pillow inside it and the mattress beneath both contribute to how well you sleep. If you are investing in quality bedding accessories, it is worth evaluating your full setup.

Many people who upgrade their pillowcases notice that their pillows are overdue for replacement at the same time. Memory foam pillows develop body impressions after two to three years, and down pillows can lose their loft over time. Our article on when to replace pillows helps you identify whether yours are still doing their job.
