Icebreaker Merino Siren Bra

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.

p>Merino wool corespunwraps Merino fibre around a super-fine nylon core to create lightweight, warm and durable garments for demanding activities. The enhanced strength and durability of the fabric retains the next-to-skin softness, breathability, temperature regulation and odour resistance of Merino wool.

The smaller themicron, 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.
