“Unlike conventional running shirts, tight-fitting ones absorb sweat and transport it to the outside—provided the material allows for it. This makes them feel consistently comfortable and cool. The X-Bionic shirts do this exceptionally well, and the Invent 4.0 Light Singlet shirt is neither too thick nor too thin, making it suitable for a wide range of outdoor temperatures or as base layer.The XL shirt fits well around the chest (my circumference is 100 cm), provides enough room to breathe, and still fits snugly around the hips (97 cm).”
