Our best-selling bra with a comfortable and lightly supportive fit, the Siren Bra features our 150gm jersey corespun fabric, which uses merino wool fibers wrapped around a nylon core for added strength and durability, while retaining next-to-skin softness.

The Siren’s sleek design and no-side-seam construction is perfect for everyday comfort and easy layering, while its thin adjustable elastic straps make for a barely-there feel.

Isabella E. ★★★★★ Oct 22, 2026

I was worried a wool bra might be itchy, but this merino jersey is incredibly soft against the skin. The light support is perfect for yoga and daily wear, and the fabric breathes so well I forget I'm wearing it.

The corespun fabric holds its shape all day without stretching out at the straps, and the lightweight support is perfect for lounging or a gentle yoga session. I've worn it three times this week already and it's been comfortable every single time, even after a full workday.

I was pleasantly surprised by how soft the merino wool feels against my skin, and the nylon core gives it just enough structure for daily wear. It’s lightweight but holds up well after several washes without losing shape.
