Frequently Asked Questions (FAQs)

1. What are the warmest thermals?

Merino wool is the best material for thermals According to Smartwool, merino wool is ultra-thin — one-third of the diameter of a human hair — and soft, unlike the prickly, itchy feel of traditional wool. Merino wool is also a sustainable choice.

2. Is base layer the same as thermal?

Thermal clothing is versatile clothing and comes in different fabrics and styles that will benefit various climates, conditions and activities. In most cases, they will be made from a synthetic material and can be called base layers, thermals or compressions.

3. What's the difference between Heatgen and Heatgen plus?

As the standard Heatgen thermals are more lightweight (read: see-through), I layer them under jeans or loungewear, but my Heatgen Plus roll-neck is opaque enough to be worn by itself and also happily happens to give me a flattering, tucked-in shape.
