Why you'll love it

  • No wires, no hooks. A soft built-in bra gives light, everyday support.
  • Cool and breathable. Silk lets air through, so you stay fresh from morning to night.
  • Smooth against skin. A smooth natural fiber with nothing scratchy against you.
  • Long enough to tuck in. Wear it alone, under a shirt or to bed.

Materials

Fabric: 100% mulberry silk, knitted for stretch (pads excluded).

What silk is made of: mulberry silk is a natural protein fiber built from 18 amino acids. That's why it feels so smooth and soft against you.

Built-in bra: soft elastic band under the bust and removable pads that slide in and out through side openings.

Details: soft bound neckline and armholes.

Still deciding? Quick answers.

Is it really 100% mulberry silk?

Yes. The tank is 100% mulberry silk, knitted so it stretches and moves with you. Only the removable pads are not silk.

Do I need a bra with it?

No. It has a built-in bra with soft pads for light, everyday support. It's not a sports bra.

Can I take the pads out?

Yes. They slide in and out through small openings at the sides.
