Our warmth system.

The bigger the number,
the warmer you'll be.

When choosing your layers, consider in which conditions you plan to use the products, and let yourself be guided by our warmth system.

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.

What is Merino?

NATURAL. ETHICAL. SUSTAINABLE.

Merino is super lightweight, soft, non-itchy, non-clammy, warm in the cold and cool in the heat, and has a miraculous ability to resist odour. Because it was made in the mountains rather than in a petrochemical laboratory. Merino wool fibre is naturally renewable, recyclable and biodegradable*.
