What makes it a Siren?
The Siren is a lightweight next-to-skin layer. It’s crafted from 150gm merino jersey corespun fabric that’s lighter than most other fabrics icebreaker use, and is made with a snug, slim fit that works perfectly as a cosy piece beneath your other layers. The Siren tees fit tighter than other tees in the range, just size up if you like a looser fit. With Corespun icebreaker wrap the superfine merino fiber around a nylon core to create a durable fabric that retains icebreaker’s signature softness, odour resistance and performance.

Material 83% wool, 12% polyamide, 5% elastane
