Just like the performance of a shell garment, the performance of a softshell garment is also significantly affected by the materials underneath it. For layering, we recommend only materials that move the body's moisture forward while being quick-drying at the same time. So try to avoid, for example, a cotton shirt, which instead of breathing absorbs moisture and dries slowly. Some natural fibers, such as merino wool, also work as the bottom layer with technical outdoor clothing. In Halti's selection you can find both technical and merino wool base layers as well as technical shirts and intermediate jackets.
