Icebreaker Women's Siren Tank Top - Black, Size M

A women's performance base layer tank top built for high-output activity, the Icebreaker Siren Tank Top combines the natural performance of merino wool with a sleek, body-hugging fit. Its Corespun fabric wraps merino fibers around a nylon core for added durability, while LYCRA® delivers four-way stretch that moves with you through every stride, climb, or yoga flow.

Advantages

Merino wool naturally resists odor, so you can wear this tank multiple times between washes. The fabric is exceptionally breathable and fast-drying, pulling moisture away from your skin to keep you cool and comfortable. Flatlock seams prevent chafing, and the scoop neck offers a flattering, feminine line that layers easily under shirts or jackets.

Suitable for

• Running, hiking, and high-intensity training
• Travel and everyday wear thanks to odor resistance
• Layering under midlayers in cool weather or wearing alone in warm conditions
• Women seeking a slim, performance-oriented fit
