Our beanies have a very soft, flexible fit that adapts to your head shape by casually wearing it. Not too tight, not too bulky.

They sit cleanly and flatter most face shapes, even if you usually don’t like how regular beanies look on you.

No. The beanie is made with a stretchy mohair outer that adapts to both small and large head sizes, creating a gentle natural grip.

At the same time, the smooth satin lining protects your hair, so the beanie stays secure without squeezing or slipping.

Yes. We carefully chose a thick mohair fabric specifically for warmth and comfort, and designed the beanie to retain heat without feeling heavy.

It’s a hair-optimised synthetic satin, not silk.

We chose it because it’s smooth on hair, durable, breathable, and fully opaque, making it comfortable and suitable to wear for Muslims as well.

I don’t know what color to choose

Choose black if you want a safe, everyday option that blends into any outfit and feels effortless.

Choose white if you want a clean, standout look that feels intentional and elevates simple fits.

Many customers get two or more because it lets them:

• Rotate styles for different outfits
• Always have one ready while the other is airing out
• Switch looks without changing comfort or fit

If you’re unsure, starting with both colors gives you flexibility without compromise.

The satin is made for all hair types. Straight, wavy, curly, coily, thick, or fine.

What makes it unique is that it was specifically developed and tested for hair protection, not fashion alone. We chose and refined this satin to minimize friction, reduce frizz, and prevent breakage, which is why it works across every hair texture.

Of course!
