A good night’s sleep should be about more than simply getting comfortable. What your skin and hair come into contact with for eight hours every night can make a noticeable difference to your bedtime routine. This is where genuine Mulberry Silk comes into its own.
At SILK SA, we have always taken a straightforward approach: uncompromising quality. Every SILK SA product is made from premium 100% Mulberry Silk in 22 Momme, rather than using lighter silk simply to reduce costs. The 22 Momme weight provides a denser, more substantial fabric with the luxurious feel, lustre and durability expected from a premium silk product.
We now offer customers a choice of two pillowcase closure styles and two hair bonnet designs. While the silk itself remains the same premium quality, each design offers a slightly different experience.
Two Pillowcase Styles: Envelope or Hidden Zipper
The most important point to understand is that the closure does not determine the benefits of the silk. Both SILK SA pillowcases use the same premium 22 Momme Mulberry Silk. The difference is primarily how the pillow is held inside the case and the look and feel of the finished pillowcase.
The Envelope Silk Pillowcase
The envelope pillowcase is the traditional, elegant approach to silk bedding. Instead of a mechanical closure, the fabric folds over at the back to create an internal flap that holds the pillow inside.
This makes it a beautifully simple design. There is no zipper, no metal or plastic component and nothing mechanical that can eventually fail.
For people who prefer simplicity and a completely soft, uninterrupted silk construction, the envelope style is an excellent choice.
The envelope design also has a timeless appearance. It is particularly suited to customers who appreciate traditional luxury and want the minimum amount of hardware or construction in their bedding.
Its main consideration is that the pillow may move slightly within the case during the night and the case can occasionally require adjustment.
The Hidden Zipper Silk Pillowcase
The hidden zipper pillowcase takes a more structured approach. The zipper is concealed within the construction, giving the pillowcase a clean, tailored appearance while helping keep the pillow securely inside.
This can be particularly appealing if you prefer your pillow to remain neatly positioned throughout the night. The finished appearance is more fitted and streamlined, with no envelope flap visible at the back.
The hidden zipper does introduce a mechanical component, however, so a little more care should be taken when washing and handling the pillowcase.
The important thing is that the hidden zipper does not make the silk itself more effective. Hair and skin come into contact with the same premium 22 Momme Mulberry Silk surface, so the fundamental benefits of choosing silk remain the same.
Which Pillowcase Should You Choose?
It really comes down to personal preference.
Choose the envelope style if you prefer:
- A traditional and uncomplicated design
- No zipper or mechanical components
- A completely soft silk construction
- Classic luxury bedding
Choose the hidden zipper style if you prefer:
- A more structured appearance
- A snugger fit around the pillow
- Your pillow staying securely inside the case
- A clean, tailored finish
Neither closure changes the quality of the silk. At SILK SA, both styles are made to the same uncompromising standard: 100% Mulberry Silk, 22 Momme and 6A Grade Charmeuse weave.
