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 makes it an Oasis Nature Dye?

Our Oasis base layers are what we’re famous for. These best-sellers are designed to contour the body and will easily flex with you, allowing maximum movement, whatever the activity. The Oasis Nature Dye fabric is dyed in natural compounds and dye stuffs producing beautiful pigment colour that will evolve and fade over time naturally. Not too heavy, not too light, it’s made from 100% merino midweight jersey, making them your go to base layers for year-round layering and everyday comfort. Enjoy the natural benefits of merino, including odour resistance and temperature regulation, keeping you warm whilst not overheating.
