Duofold Insulayer thermal underwear

Duofold insulayer long underwear keeps you warm and comfortable through the clever use of 2 layers of fabric.

The outer layer is made of warm merino wool. The inner layer is made of 100% cotton. Which makes this the long underwear of choice for anyone with sensitive skin, or who would find wool itchy.

The air trapped between the two layers of fabric forms a 3rd insulating layer that traps heat, without adding any weight.
