The Soleie Shirt merino undergarment by Bergans impresses all on every front, as it is made of the highest quality material. The material in question is incredibly comfortable merino wool. This type of wool is known for being soft on the skin and preventing chafing. This means the shirt can be comfortably worn directly on the skin. Aside from being incredibly comfortable, the merino wool is also impressively warming. That remains true even when it is damp. Even when the shirt has absorbed sweat, it still keeps you warm.
