The Long Johns with Fly 400 are made using a circular knitting process, eliminating the need for longitudinal seams and ensuring exceptional wearing comfort. The merino wool provides optimal temperature regulation due to its crimped structure. Even when damp, the material retains warmth and is comfortable and non-itchy against the skin. With a fly opening.

These thicker garments are designed as a mid-layer to enhance thermal insulation between the close-fitting functional underwear and the outer layer, which is worn for protection against wind and moisture. They are particularly useful in lower temperatures or during less intense activities.

This is a knitted terry fabric, with one side being smooth and the other consisting of terry loops. The airy terry loops combined with the crimped structure of the wool create a knit that traps a significant amount of air, resulting in excellent insulation properties. The thicker the layer of air next to the body, the less body heat can escape.
