The one that sells out before we can keep up with it. Sage is our single most popular colour — and it has been since the day we launched it. There's something about this particular shade of green that just works for everyone, in every bedroom, in every season.
It's not quite grey, not quite green — it sits in that perfect middle ground that's simultaneously calming, sophisticated, and effortlessly on-trend without ever feeling like it will date. Customers who buy Sage almost always come back for a second. Only 4 left in single.
Crafted from 22 momme 100% 6A grade mulberry silk in our signature boomerang shape, this pillowcase is designed specifically for side sleepers — with a gentle curve that cradles your face, neck, and shoulder to reduce pressure and support a more comfortable sleeping position through the night.
The ultra-smooth silk surface creates minimal friction against your skin and hair as you move during sleep, a noticeable step up from traditional cotton pillowcases. The naturally non-absorbent fabric means your overnight skincare stays on your face where it belongs. Breathable and naturally hypoallergenic, it's a wonderful choice for those with sensitive skin who prefer a gentler surface to rest on.
Sage pairs with literally everything — white, ivory, copper, charcoal, blush, linen, terracotta. It also features in our Green Obsession Trio (Dark Green + Olive + Sage) and our Copper + Sage duo for those who want to build a full collection.
Why silk? Silk's smooth surface creates far less friction than cotton as you move during sleep — helping your hair stay smooth and your skin feel comfortable when you wake up. Naturally hypoallergenic and resistant to dust mites, it's a wonderful choice for those with sensitive skin.
Handmade in small batches using 22 momme 6A grade mulberry silk.
Note: This pillowcase is designed to fit boomerang-shaped side-sleeper pillows — commonly called U-shaped, V-shaped, or L-shaped pillows. Please check measurements before purchasing if using with a similar-shaped pillow you already own.

Silk benefits
Healthier Hair with Silk Pillowcases
Discover the Science Behind Silk’s Hair Benefits
Silk pillowcases reduce hair frizz and breakage due to their smooth surface. Silk contains two key proteins—fibroin and sericin—that are naturally hypoallergenic and help maintain hair’s moisture balance. Fibroin provides a silky, smooth texture, while sericin acts as a protective barrier, reducing friction and preventing damage. This means less tangling, fewer split ends, and healthier, shinier hair every morning.
