When choosing your outdoor equipment, you will encounter two stars - softshell and fleece. Two popular materials, which are directly designed for active movement outdoors. And they work best together!
While soft and lightweight fleece is responsible for thermal protection, the breathable and durable softshell provides protection against inclement weather and allows the sweat to evaporate through the fabric.
Fleece sweatshirts and softshell jackets can be worn separately of course, but if you're looking for an unbeatable duo, with whom you never loose your nerves, softshell and fleece are your obvious choice.
And I will not disappoint even in winter. Just add a third layer of functional clothing - underwear.
