You can not choose the weather on the day of the competition. You can not ask for twenty-two degrees and changing cloudiness. When the weather report predicts sunny and warm weather, you need to have equipment that allows you to fly. Like this ultralight and soft runner t-shirt from adidas. Breathable fabric helps you withstand the heat. 3-Stripes in the form of brushstrokes inspired by Japanese calligraphy will help you feel fast.
