Women’s Merino 150 Siren Bra

Meet the Women's Merino 150 Siren Bra by Icebreaker, the brand's beloved everyday bra built from soft merino corespun jersey. With a streamlined silhouette, no side seams, and thin adjustable straps, it delivers a barely-there feel that still offers light support. It's designed to live under tees, dresses, and base layers without adding bulk.

Key Features:

• 150 g merino corespun fabric—merino wrapped around a durable nylon core with added stretch.
• No-side-seam construction for a smooth, chafe-minimizing fit.
• Thin, adjustable elastic straps so you can customize your fit and coverage.
• Light-support design ideal for everyday wear, travel, and low-impact activity.

Why It's Good:

• Merino wool is naturally breathable, odor-resistant, and temperature-regulating, making it perfect against the skin.
• Long-wearing merino basics reduce the total number of bras you need in rotation.
• Icebreaker's focus on merino traceability and animal welfare supports more responsible fiber sourcing.

Fit & Care: Lightly supportive, close fit; stick with your usual bra or sports-bra size. Machine wash warm or cold in a lingerie bag and line dry to protect the straps and fabric.

Style Notes: Team your Icebreaker Merino 150 Siren Bra with Siren bottoms or Sprite styles for a coordinated merino set that moves easily from everyday life to weekend adventures.
