Frequently Asked Questions (FAQs)

1. Are base layers the same as thermals?

While some may argue that there is a difference between a thermal and base layer, they are essentially the same thing. No matter what you want to call them, thermals are designed to wick away moisture, regulate your body heat, and stretch so you can move freely.

2. What is the warmest material for thermals?

1. Angora Wool. Angora wool is a soft luxurious fibre. The fibres are hollow, and it is one of the warmest natural fibres you can get - up to seven times warmer than sheep's wool - making ideal for use in thermal underwear.

3. What is the best base layer material for cold weather?

Merino Wool: The other more common type, a merino wool base layer is made of a gentler type of wool that's less irritating to the skin. It excels at regulating body temperature, so it's great for insanely cold weather but won't have you overheating when things start warming up.
