How does thermal material work to keep you warm?

The thermal material that is used in most of our products is merino wool. This is because we believe it is the best fabric to keep you warm while offering a whole range of other benefits. Below we describe how thermal materials works to keep you warm. 

Merino wool is taken from the merino sheep that live in the southern alps of New Zealand and survive extreme temperatures of 35°c in the Summer and -20°c in the Winter. The reason they survive is because of their wool fleece. This clever coat is temperature regulating meaning the sheep are kept cool in the Summer and warm in the Winter. The reason merino wool works so great for thermals is because it retains these amazing temperature regulating properties when made into clothing. 

Merino is an active fiber which takes in factors such as the wearer's body temperature and external conditions to ensure your body is kept as the perfect temperature. In cold conditions your merino thermals will keep you warm, and in warm conditions they will keep you cool. 

Another way that merino wool keeps you warm is that it wicks moisture away from the skin and into the atmosphere meaning you'll be kept drier for longer. Merino can absorb up to 35% of it's own weight before feeling wet.

As well as the above benefits, merino wool is also


Unlike regular wool, merino wool doesn't irritate the skin and therefore doesn't itch. The merino fibres are so fine that when in contact with the skin they bend. It is also hypoallergenic meaning it's great for people with eczema or allergies.

Odour Resistant:

The lanolin in merino wool prevents mildew and bacteria from building up on your clothing and any odour molecules are absorbed into the merino fibre stopping the build up of unpleasant odours.

Long Lasting:

Although merino wool clothing tends to be more expensive than synthetic clothing it will last a lot longer meaning you won't have to repurchase every few months. Merino wool fibres can bend over 20,000 times without breaking so won't lose shape or get holes.

Merino wool thermals are perfect for everyday use in the winter and also for outdoor activities such as cycling, hiking and snowsports.
