Why are arm warmers, leg warmers, and knee warmers necessary for a cyclist? Because on those days with changeable weather you do not want to be surprised during your ride. With arm warmers, you can easily turn your short cycling shirt into a long one when the wind gets cold. If you set off early in the morning and it is just too cold for short cycling shorts, you can easily put on leggings. When the temperature rises, you can take them off again in a flash. Knee warmers protect your knee joints from the cold so that they are less likely to get injured. But beware, choose your arm and leg warmers carefully depending on the temperature.
