SLIP Silk Pillowcase King - 100% Mulberry Silk 22 Momme, White - Anti-Bedhead & Anti-Sleep Crease

The SLIP King Pure Silk Pillowcase is a 100% mulberry silk, 22 momme king-size pillowcase designed to reduce sleep creases, minimize bed head, and protect hair and skin overnight.

Made from highest-grade long-fiber mulberry silk (6A) with a 22 momme weight, this king pillowcase (20" x 36" / 51 x 76 cm) combines luxury and performance. An invisible zipper keeps the pillow secure while machine-washable construction and non-toxic dyes make it suitable for regular use. SLIP developed this fabric over a decade to balance sheen, durability, and softness for nightly comfort.

How does a silk pillowcase help reduce sleep creases and bed head?

Silk’s smooth surface reduces friction between your skin, hair, and the pillow, so fewer creases form and strands are less likely to tangle or break. Clinical-style user feedback shows most people notice visibly fewer lines and less morning frizz after switching to this slip silk pillowcase.

• 22 momme silk provides a dense, smooth weave that glides across skin and hair.
• Reduces fabric friction by about 43% compared with cotton, helping preserve hairstyles.
• Over 95% of users reported reductions in sleep creases and visible lines.

Is this pillowcase safe for sensitive skin and easy to care for?

SLIP’s mulberry silk is naturally hypoallergenic and made with non-toxic dyes, making it a gentle option for many skin types. The pillowcase is designed for simple home care—use the gentle cycle and low-heat drying or air-dry to maintain softness and longevity.

• Hypoallergenic silk resists common irritants and allergens.
• Non-toxic dyes minimize skin reactions and preserve color integrity.
• Machine-washable on a gentle cycle; follow care tag instructions to extend life.

What makes SLIP’s silk different from cotton or synthetic satin alternatives?

SLIP’s pillowcases use 6A long-fiber mulberry silk at a 22 momme weight, which gives a balance of sheen, strength, and substance not found in lower-quality satin or lightweight silk. Users report better moisture retention and a more luxurious feel, with many preferring SLIP over traditional cotton or synthetic fabrics.

• 6A grade long-fiber mulberry silk offers superior durability and luster.
• 22 momme thickness resists wear while feeling substantial and soft to the touch.
• Over 92% of users preferred SLIP to cotton or synthetic satin alternatives.

Will a silk pillowcase affect my skincare or hair products?

Because silk absorbs far less product than cotton, more of your night creams and serums remain on the skin, and oils and styling products are less likely to be absorbed into the fabric. This helps your routine stay effective overnight while reducing product waste on pillows.

• Silk absorbs significantly less face cream than cotton, preserving product benefits.
• Lower absorption means less product buildup on bedding and longer-lasting skin treatments.
• Smoother surface reduces pulling on delicate facial skin and hair fibers.

Who is this for: The SLIP King Pure Silk Pillowcase is aimed at anyone seeking a premium sleep surface—people focused on minimizing sleep lines and frizz, those with sensitive or reactive skin, and anyone who values a durable, luxurious pillowcase for nightly use. It’s especially suited to those who prefer a larger king-size pillow and want an easy-care option that integrates into a beauty or haircare routine.
