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.
