Dunno what it says underneath, but that image is mirrored.
Done that in the past, if I ride at a decent pace I will deepfreeze my hands, knees and face while overheating underneath everything covered in clothes.
Not optimal clothes. Ski-pants with winter boots with thermal socks, windcheater, mask on the face and some proper gloves. Works for me. Average speed of 13-15km/hour.
