A soft and stretchy women’s T-shirt with an updated fit and fabric that makes it even more comfortable, the Siren Long Sleeve Sweetheart is made with Icebreaker's corespun fabric, soft merino wool fibres wrapped around a nylon core for added strength and durability, while retaining next-to-skin softness. Ideal for year-round use whether traveling, hiking, or relaxing after a big day outside, the Siren Long Sleeve Sweetheart also features a flattering neckline and a fit that’s perfect for everyday comfort and layering.
Corespun wraps Icebreaker's superfine merino fibre around a high denier nylon core to create a durable fabric that retains Icebreaker’s signature natural softness against the skin, odour resistance and temperature regulating performance.
Growers who sign contracts to provide wool to Icebreaker agree not to use mulesing on their sheep. Icebreaker guarantees your garment is mulesing-free.
Icebreaker is committed to animal welfare, the well-being of the people who work with them and the environment. That's why Icebreaker created the Baacode – so people can see exactly where their garment came from. Customers can see the conditions the sheep live in, get to know the sheep farmers and track the production process from fibre to the final product.
