Our fabric numbering system.
The bigger the number, the warmer you'll be.
Choose your comfort level with our fabric weight numbering system. The numbers represent the fabric's weight in grams per meter2.
Our merino fiber measurement.
The smaller the micron,
the finer the fiber,
the softer it feels.
The diameter of a merino fiber is measured in microns – where one micron equals one millionth of a meter.
icebreaker’s merino fibers range from 15.5 – 23.5 microns to ensure a soft hand feel across our skin to outer layers. Finer fibers feel softer because they bend more easily when in contact with the skin.

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 we use, and is made with a snug, slim fit that works perfectly as a cosy piece beneath your other layers. Our Siren tees fit tighter than other tees in our range, just size up if you like a looser fit.
With Corespun we wrap our superfine merino fiber around a nylon core to create a durable fabric that retains icebreaker’s signature softness, odour resistance and performance.
