Color: Black with gray stripes Dimensions: Width 51cm, Length 66cm I used to carry this to prevent my body temperature from dropping when going downhill on a road bike. It's very light and can be folded compactly. There are mesh ventilation panels on the upper back and in the three pockets, allowing you to open the zippers and adjust the temperature when it gets hot. It's also convenient for running. The cuffs and waist have elastic to prevent wind from entering. The fit is not loose, but rather light and snug.
