When you’re choosing a silk pillowcase, most of the attention goes to the silk itself, momme weight, grade and whether it’s real Mulberry silk. But the way your pillowcase closes matters too.
The two most common options are zippered silk pillowcases and envelope-style pillowcases. Both can give your hair and skin a smoother sleep surface, but they behave a little differently once they’re actually on your bed.
What is a zippered silk pillowcase?
A zippered pillowcase uses a concealed zip to keep the pillow securely inside the case. The biggest advantage is simple: it stays put.
If you move around in your sleep, a hidden zipper helps stop the pillow from shifting or working its way out of the case overnight. It also creates a cleaner, more fitted finish on the bed. At Kova Silk, our silk pillowcases use a hidden zipper so you get the security of a zip without a bulky closure sitting against your hair or skin.
What is an envelope pillowcase?
An envelope pillowcase has an internal fabric flap that folds over the end of the pillow.
The finish is simple and soft, with a looser, more traditional feel than a zippered style.The trade-off is that the pillow can shift inside the case a little more easily, especially if you’re a restless sleeper.
Is a zippered silk pillowcase better?
It depends on what matters most to you. A hidden zipper can be a better fit if you want:
- a pillowcase that stays securely in place
- a neater, more fitted look
- less pillow movement during the night
- a cleaner finish around the edge of the pillow
An envelope closure may suit you if you prefer a softer, more traditional finish and don’t mind a slightly looser fit.
The silk itself is still the most important part for your hair and skin. The closure simply changes how the pillowcase fits, looks and stays in place overnight.
What should you look for in a silk pillowcase?
Closure style is only one part of the decision.
Look for:
- 100% Mulberry silk
- a substantial momme weight for regular use
- a smooth finish with less friction against hair and skin
- a closure that suits the way you sleep
- clear care instructions
Kova Silk pillowcases are made from 100% 6A Mulberry silk in a 22-momme weight, with a hidden zipper for a secure fit night after night.
Because the best silk pillowcase isn’t just the one that feels good when you put it on the bed. It’s the one that still feels right at 6am.
