Made From Cool-Lite™ Jersey, 60% TENCEL™, 40% Merino wool 18.9 micron (Exclusive of decoration)

Merino wool is super lightweight, soft, moisture-wicking, 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. It's naturally renewable, recyclable and biodegradable.

ZoneKnit™: is a body-mapped knitting technology that features different types of fabrics and technologies in the one garment to create warmth and ventilation in the places you need them most to optimise all-day comfort and built-in stretch so you can move freely. Naturally breathable and odour resistant.

Cool-Lite™ combines Merino wool and TENCEL®, a natural fibre sourced from sustainable eucalyptus plantations, so bringing together two natural, low environmental impact fibres. The high natural moisture content of TENCEL® keeps you cool in the heat yet remains dry to the touch and is 60-70% cooler than Merino wool alone, as well as having exceptional wicking abilities (50% more moisture absorbed than cotton and dries twice as fast as polyester). The Merino wool component resists odour, breathes, and regulates temperature when it turns cooler. Defeat the heat in comfort.

The smaller the micron, the finer the fibre, the softer it feels. The diameter of a Merino fibre is measured in microns – where one micron equals one millionth of a metre. Icebreaker's Merino fibres range from 15.5 to 23.5 microns to ensure a soft hand feel across our skin to outer layers. Finer fibres feel softer because they bend more easily when in contact with the skin.

  • Icebreaker next-to-skin layers: 15.5-18.5 micron
  • Icebreaker mid layers: 18.6-22.5 micron
  • Icebreaker outer layers: 22.6-23 micron
  • Synthetic fibres: 30 micron
  • Traditional wool fibre: 50 micron
  • Human hair: 70 micron
