Merino: nature's performance fiber
What makes merino an incredible natural performance fiber and beautiful fabric to wear?
The merino fibre can actively manage moisture by absorbing from the skin and then desorbing to the atmosphere, leaving you dryer and more comfortable. A merino fibre will absorb up to 35% of its own weight in water before feeling wet, much greater than most synthetic fibres.
Wool fibre has very good extensibility and can be extended by more than 30% of its length without breaking and, in turn, can recover from extensions of approximately 20%. Merino wool also has an intrinsic wavelike structure called crimp making it more resilient.
Fine fibres from sheep such as merino, are comfortable and soft enough to be worn next to the skin. icebreaker Merino fibres are so fine that when in contact with the skin they simply bend, providing softness and comfort.
Merino is naturally flame resistant, and its performance exceeds that of all other commonly encountered textile fibres. If merino comes into direct contact with another burning surface, it won’t melt or stick.
Merino is a technically active fibre, which has the ability to gain and release heat depending on the wearer's next-to-skin environment and the external conditions. As merino absorbs moisture it releases a small amount of heat, and in hot conditions the reverse effect occurs. This means you stay warmer in cold conditions and cooler in hot conditions. It's like wearing your own personal air conditioning system.
Merino outperforms other fibres with its ability to resist the build-up of unpleasant odours. Odour molecules are absorbed into the merino fibre, effectively becoming trapped and less readily detected by the human nose.
All the perks of wool - odor control, temperature regulation - plus one more: unparalleled comfort.
