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.

Thermal comfort levels with our fabric weight range from 125 for warm conditions to 400 for cold conditions.

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’s unique about the Vertex base layer?

A heavy weight base layer with a twist, our Vertex series feature shapes and patterns for added fun. The fabric is double knitted, meaning it’s thicker for added warmth while retaining lightness in weight. The jacquard jersey fabric also has unique patterns knitted in, with designs inspired by nature. Made from 100% merino for natural odour resistance and temperature regulation so even when it’s keeping you warm, your body can breathe.
