The Benefits of Wearing Thermal Underwear

Warmth, moisture control and being lightweight are key benefits. Thermal underwear traps body heat close to the skin, making them the perfect base layer choice to keep you warm during cold temperatures. 

Why Choose Merino Wool Thermals?

We recommend merino wool thermals, and a major strength of natural merino wool is that they are resistant to odour, allowing to being worn for long periods. Unlike regular cotton, merino wool base layers pull sweat away from your skin, keeping you dry and preventing that sudden chill when you stop moving.
