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.
