Warm in winter, cool in summer
Wool fibres breathe. They trap air when it is cold and let heat and moisture escape when it is warm, so a sheepskin feels right all year round.

Why sheepskin
We could list clever technologies here. Sheepskin does not need any. Everything that makes it so good to live with comes built in.
Wool fibres breathe. They trap air when it is cold and let heat and moisture escape when it is warm, so a sheepskin feels right all year round.
Wool naturally carries lanolin, a wax that shrugs off dirt and moisture. A good shake and some fresh air is most of the cleaning a sheepskin will ever ask for.
Soft, dense and free from the static of synthetics. There is a reason people have slept, sat and wrapped themselves in sheepskin for thousands of years.
