150 MerinoFine Ace Women's SS Tee

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 under certain conditions.

OTW® Omega Twist Spinning Technology creates superior garment construction that improves the longevity of the garment and meets the demands of activewear: reduced pilling, more abrasion resistance, more production yield during the manufacturing process and reduced mending and finishing costs generally needed to construct the best worsted Merino wool fabrics. The overall functional enhancement of Merino wool garments made from OTW® yarns elongates their life cycle and, thereby, improves the environmental impact of every product containing them.

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
