In contrast to synthetics, Merino is an active bre that reacts to changes in body temperature. So, it helps you stay warm when the weather is cold, and cool when the weather is hot.
Merino fibres can absorb large quantities of moisture vapour then move it away to evaporate into the air. So Merino wool clothing is extremely breathable and less prone to clamminess.
Merino fibres are extremely fine, enabling them to bend far more than traditional, coarser wool fibres. This makes Merino wool feel soft and luxuriously gentle next to your skin
