Thermal Base Layers
Thermals, or base layers as they're often referred to, are moisture-wicking items of clothing designed to keep your body heat trapped closed to your skin. Made from merino wool or synthetics such as polyester, base layers are best paired with a mid layer that keeps you warm and an outer layer that is waterproof and protects you from the snow, wind and rain. Thermal underwear, tops and bottoms are ideal for any winter or cold climates whether you wear them for everyday use, mountain climbing or skiing.
What is the point of wearing a base layer?
Thermal clothing offers several benefits though it is, of course, a personal preference if you opt to wear one. Some of the advantages to wearing thermal underwear, pants or tops include regulating your core temperature while still allowing for air flow and being moisture-wicking to remove perspiration. Thermals also tend to be lightweight so that you can easily layer over the top without restricting flexibility and should repel or resist odour.
What are the benefits of Merino wool?
Merino wool is a natural fibre and one of the finest wools produces across the globe. Using sustainable farming practices, Merino sheep produce new fleece every year which makes merino wool a renewable fibre. Thinner and softer than your standard wool, merino is lightweight and breathable yet warm – and warmer still as the density of the wool increases. Merino wool is also antimicrobial which, killing odour causing bacteria, and hydroscopic, absorbing and releasing moisture from your skin. It can also absorb up to 35% of its bodyweight in moisture before it begins to feel damp yet keep you warm when it's wet.
