Next-to-Skin Comfort and Wire-Free Support for Every Day

The foundation of any great outfit starts with comfortable underwear. The Icebreaker Women's Siren Bra is a sleek, wire-free bralette designed to provide soft, natural support without the restrictive pinching of traditional bras. Crafted using Icebreaker’s signature Corespun fabric—where super-fine Merino wool is wrapped around a nylon core—it delivers the ultimate combination of next-to-skin softness, moisture-wicking breathability, and long-lasting durability. With adjustable straps and space for cup inserts, it is a versatile daily essential you will forget you are even wearing.

Why We Love It

At X-Boundaries, we consider this the ultimate travel and everyday bra. We love it because it completely eliminates the discomfort of underwires, making it a dream for long-haul flights or lounging around camp after a long trek. Because it utilizes the natural odor-resistant properties of Merino wool, it stays fresh significantly longer than synthetic sports bras, allowing you to pack less and wash less on your adventures.

Key Features

Corespun Fabric Technology: Features Merino wool wrapped around a durable nylon core, providing the natural softness of wool with enhanced strength and longevity.
Wire-Free Support: Designed without underwires for pinch-free, all-day comfort that moves naturally with your body.
Adjustable Straps: Sleek, easy-to-adjust shoulder straps allow you to dial in the perfect, personalized fit.
Customizable Cups: Features discreet side openings with space to add your own bra cup inserts for additional shape and coverage.
Naturally Odor-Resistant: Merino wool naturally resists bacteria buildup, keeping you feeling and smelling fresh even after long days of travel or light activity.

Care & Maintenance

To preserve the natural elasticity and softness of your Merino wool blend, follow these simple care instructions:

Washing: Machine wash cold or warm on a gentle cycle with like colors.
Drying: Line dry in the shade. Do not tumble dry, as high heat can damage the elastic and shrink the wool fibers.
Treatments: Do not use bleach. Strictly avoid fabric softeners, as they coat the Merino fibers and destroy their natural ability to wick moisture and resist odors. Do not dry clean.
