Merino wool is a natural, sustainable and biodegradable fabric.

It is one of the smoothest and softest wools of any sheep, so it feels really great next to your skin.

It also has inherent qualities that make it ideal for life in the great outdoors.

In cold weather it regulates your body temperature by trapping air in the pockets between its tiny fibres - this locks in your body heat.

If you then start heating up, it also keeps you cool as its fibres have a natural affinity for water, so they draw the moisture away from your skin.

It is also exothermic, this means it maintains its warmth when wet.
